Answer:
g(f(x)) = x . . . so the functions are inverses
Step-by-step explanation:
Two functions f and g are inverses of each other if ...
g(f(x)) = x or f(g(x)) = x
We are asked to evaluate g(f(x)). That will be x if the functions are inverses.
g(f(x)) = g((x+1)/2) = 2((x +1)/2) -1 = (x +1) -1
g(f(x)) = x . . . . the functions are inverses
You distribute the 30x to the equation in parenthesis
So basically you are doing (30x*x)+(30x*-3)
So you get 30x^2-90x
Hope this helps!
Answer:
y=(2/3)x-1
Step-by-step explanation:
The slope is (1-(-1))/(3-0) = 2/3
And the y intercept is -1,
Therefore: y=(2/3)x-1
The vertex is (-3,3),so a =-3, b=3. a+b=0
