Answer:
Let's replace the h(x) function in g(x) and then use 74 as a result on the axis y. The correct answer is 4 .
Plug the given x and y values (x, y) into the equations and solve
It look like the second equation is the answer.
Answer is a1 = 7
Using equation (derived from formula to find sum of values in a geometric series),

Hence, solve for a.
The answer is 1 19/25
