When we are given a function f(x) and we are asked for f(a) [a is any number], it means to replace (or substitute) a into x in the function (x=a)
In this problem, we are asked to replace x with 2 in f(x), the first equation, and replace x with 3 in the second equation.
It looks like this:
f(2) = 2^3 + 5(2)^2 = 8 + 5(4) = 8 + 20 = 28
g(3) = 2(3) + 4 = 6 + 4 = 10
We finally just add these two numbers from f(2) and g(3) and get 28 + 10 = 38

Step-by-step explanation:
di kasi ako magaling sa math
Answer:
H: 0, 1, 2, 3, 4, 5
plumber 1: 20, 70, 110, 160, 210, 260
plumber 2: 0, 60, 120, 180, 240, 300
plumber 1: C = 50h + 20
plumber 2: C = 60h
Since it's normally distributed, we can apply the emperical rule. The middle 95% will be within two standard deviations of the mean, so that means:
18-2(1.5), 18+2(1.5)=15,21
So we want the first option.
0.7 or 0.70 can be your answer
