Answer:
f(4) -g(4) = 2
Step-by-step explanation:
Fill in the given values for x and do the arithmetic.
f(4) = 9·4 -2 = 34
g(4) = 2·4^2 = 32
Then ...
f(4) -g(4) = 34 -32
f(4) -g(4) = 2
ANSWER= 2
Explanation
Plug in the numbers in the parentheses for x EX: f(4)=9(4)-2= 34 and g(4)=2(4)^2 —-> g(4)=2(16)= 32 so 34-32= 2
