Question

PLEASE HELP!!!!!! IMA DESPRATE!!!!!!Determine whether f(x) = 2x3 − 6 is linear. If so, give the slope and y-intercept.

Answer 1

The slope of the cubic polynomial and it's y-intercept are respectively; f(1) = -4 and f(0) = -6

What is the slope of the equation?

We are given the equation;

f(x) = 2x³ - 6

Now, because the highest power of x is 3, it means that this is a cubic polynomial and not linear because it has a degree of 3

Thus, let us differentiate to get the slope;

f'(x) = 6x² - 6

At f'(x) = 0; x = 1

Thus, slope is;

f(1) = 2(1)³ - 6

f(1) = -4

y-intercept is f(x) at x = 0. Thus;

f(0) = 2(0³) - 6

f(0) = -6
