Answer to Use a table of values of f(x)= \sqrt{x^2 x 6} x to guess the value of the limit Prove that your guess is correct by evaluatingThe function f (x) is represented by this table of values x f (x) 5 28 3 121 4 0 3 1 4 3 12 5 28 Match the average rates of change of f (x) with the corresponding intervals Tiles 2But let's use "f" We say "f of x equals x squared" what goes into the function is put inside parentheses after the name of the function So f(x) shows us the function is called "f", and "x" goes in And we usually see what a function does with the input f(x) = x 2 shows us that function "f" takes "x" and squares it

See Answer Check out a sample Q&A here Want to see this answer and more? Your function g (x) is defined as a combined function of g (f (x)), so you don't have a plain g (x) that you can just evaluate using 5 The 5 needs to be the output from f (x) So, start by finding 5=12x That get's you back to the original input value that you can then use as the input to g (f (x)) Subtract 1 4=2xPractice Creating a Table of Values Create a table of values of the equation y = 5x 2 Create the table and choose a set of x values Substitute each x value (left side column) into the equation Evaluate the equation (middle column) to arrive at the y value

We can see that table of values for f(x) show identical values for f(x) and f(x), the function is even We can say the same for the values shown for g(x), so the function is even The lefthand side of the tables are the negative values of the one on the side, so the function is oddThere are two tables here The first one gives critical values of F at the p = 005 level of significance The second table gives critical values of F at the p = 001 level of significance 1 Obtain your Fratio This has (x,y) degrees of freedom associated with it 2 Go along x columns, and down y rows This problem has been solved!

The graph of f (x)=x^2 is called a "Parabola" It looks like this One of the ways to graph this is to use plug in a few xvalues and get an idea of the shape Since the x values keep getting squared, there is an exponential increase on either side of the yaxis You can see this by plugging in a few values When x=0, f (x)=0Use the table of values of f(x,y) to estimate the values of f x (3,2),f x (3,22),and f xy (3,2) View transcribed image text fullscreen Expand check_circle Expert Answer Want to see the stepbystep answer?Derivative examples Example #1 f (x) = x 3 5x 2 x8 f ' (x) = 3x 2 2⋅5x10 = 3x 2 10x1 Example #2 f (x) = sin(3x 2) When applying the chain rule f ' (x) = cos(3x 2) ⋅ 3x 2' = cos(3x 2) ⋅ 6x Second derivative test When the first derivative of a function is zero at point x 0 f '(x 0) = 0 Then the second derivative at point x 0, f''(x 0), can indicate the type of that point

Again we graph \(f(x)\) and create a table of its values near \(x=0\) to approximate the limit Note that this is a piecewise defined function, so it behaves differently on either side of 0 Figure 17 shows a graph of \(f(x)\), and on either side of 0 it seems the \(y\) values approach 1 Note that \(f(0)\) is not actually defined, asGraph the exponential problem F(x)=3 x Hi Jose, Set up b and extend the table to x F(x) 1 3 1 = 3 2 3 2 = 9 3 3 3 = 271 31 = 1/32 32 = 1/93 33 = 1/27 Also 3 Determine all values of x for which each function is discontinuous F(x)= 3x4 / 4x^2 2x 2 math The function f(x)=ax^3x^3bx24 has three factors Two of these factors are x2 and x4 Determine the values of a and b , and then determine the other factor
