Find x^3- 2y^2- 3x^3+ z^4 if x = 3, y = 5, and z = -3 the upward arrows means that it is squared, cubed, etc hurry

-721

Step-by-step explanation:

true !

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
