1) Find g (4) by substituting 4 in place of x in g (x).
g(4) = 4^3 = 64
2) Substitute 64 in place of the x in f(x)
f(64) = 2(64) + 5
= 128 + 5
= 133
You would have to be 30 because multiples of 5 would only be 25 and 30 inbetween those numbers, and 25 is not an even number which it must be if you can say the number counting by 2s
Since the equations are for absolute value this means any negative number used the answer would become positive, so to get the lowest value possible x would need to equal 0, which would eliminate the x variable from the equations.
Replace x with 0 and solve:
|5(0)^2 - 16| + |10(0) - 2|
Simplify:
|0 - 16| + |0 - 2|
|-16| + |-2|
Combine:
|-18|
Absolute Value = 18
