Answer:
20.
Step-by-step explanation:
2x + x - y^2; x = 8 and y = 2.
2(8) + 8 - (2)^2
= 16 + 8 - 4
= 24 - 4
= 20.
Hope this helps!

Step-by-step explanation:
let f(x) = y, then
y = 4x + 12
To obtain the inverse g(x), rearrange making x the subject
4x + 12 = y ( subtract 12 from both sides )
4x = y - 12 ( divide both sides by 4 )
x =
Change y back into terms of x
g(x) = ← inverse of f(x)
