PSAT Math Grid-Ins Question 130: Answer and Explanation
Question: 130
If f(x) = 7x + 3 and g(x) = 2x2, what is the value of f(g(1))?
Correct Answer: 17
Explanation:
17 Work inside out by first solving for g(1):
g(x) = 2x2 → g(1) = 2(1)2 = 2.
Then put 2 in for x in the f (x):
f (x) = 7x + 3 → f (2) = 7(2) + 3 = 17
