Answer:
57
Step-by-step explanation:
range = biggest - smallest
91 - 34 = 57
range = 57
First of all, we compute the points of interest, i.e. the points where the curve cuts the x axis: since the expression is already factored, we have

Which means that the roots are

Next, we can expand the function definition:

In this form, it is much easier to compute the derivative:

If we evaluate the derivative in the points of interest, we have

This means that we are looking for the equations of three lines, of which we know a point and the slope. The equation

is what we need. The three lines are:
This is the tangent at x = -2
This is the tangent at x = 0
This is the tangent at x = 1
Answer:
D
Step-by-step explanation:
Answer:
If both sides are equal
Step-by-step explanation:
If both sides are equal and are the same in both sides of the equation, than it is a solution.
For instance, the solution for 2x = 4, is x = 2 because 2(2) = 4 is 4 = 4.
