Your answer would be
2(13+9x)
Step-by-step explanation:
Answer: x = −18
Step-by-step explanation:
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + -1x = 22 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 22 + -4
-1x = 22 + -4
Combine like terms: 22 + -4 = 18
-1x = 18
Divide each side by '-1'.
x = -18
Simplifying
x = -18
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.
