Which of these functions has an inverse function? select all that apply.
y = x
y = x^2
y = x^3
y = x^4

ANSWER

y=x

y=x³

EXPLANATION

A function, f(x) has an inverse if and only if

Thus, the function is one to one.

For y=x or

Hence this function has an inverse.

For the function y=x² or f(x)=x².

This function has no inverse on the entire real numbers.

For the function y=x³ or f(x)=x³

This function also has an inverse.

For y=x⁴ or f(x) =x⁴

This function has no inverse over the entire real numbers.

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
