Which restriction would enable the function
f(x) = x² + 6x - 9 to have an inverse function?

Which restriction would enable the function f(x)= x² +6x-9 to have an inverse function? The domain of the function f(x)=(x+2)2+3 is restricted to (-8,-2] to produce an invertible function g(x)=(x+2)2+3.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
