What is the y-intercept of the polynomial f(x) defined below? Write the y- value only.
f(x) = -7x – 2x3

Y-intercept = 0 ( aka. (0,0) )

Step-by-step explanation:

The y-intercept of a function is found when x=0:

f(x) = -7x - 2x³

f(0) = -7(0) - 2(0)³

f(0) = 0 - 0

f(0) = 0

Therefore, the y-intercept of the polynomial is 0. You can also say that it is 0 because a cubic function is symmetrical about the origin.

w'x is 0.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
