Answer:
y = 1/5x + 32/5
Step-by-step explanation:
(2x/-5x)+x^2
(x(2)/(x(-5))+x^2
(-2/5)+x^2, the x values cancel in numerator and denominator and simplify to -2/5
Answer:
See explanation
Step-by-step explanation:
You are given the function 
The domain of the function are all possible values of variable x, so you can find f(x) for x=-2, 0, 3, 5:

The table is

The inverse function
has the domain which is the range of the function f(x) (all possible values of f(x)), so the domain of inverse function is {-7,-1,8,14}
By cross-multiplying, we get
15x + 30 = 24
15x = -6
x = -3 / 5
