Which function, g or h, is the inverse function for function f? A. the function h because the graphs of f and h are symmetrical about the line y = x
B. the function g because the graphs of f and g are symmetrical about the line y = x
C. the function h because the graphs of f and h are symmetrical about the x-axis
D. the function g because the graphs of f and g are symmetrical about the x-axis

yes

step-by-step explanation:

give me the question

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
