Answer:
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.
