Pre-calculus, i need major . tutoring has done almost nothing for me and i'm majorly confused, explanations and any would be greatly appreciated!

y = ±(x/4)^¼; f⁻¹(x) is not a function

Step-by-step explanation:

y = 4x⁴

To find the inverse, switch x and y, and solve for y.

x = 4y⁴

x/4 = y⁴

y = ±(x/4)^¼

This is not a function.  Because of the ±, y can have two values for any non-zero value of x.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

not sure but it may be b, as i said i'm not sure.
