Question

If f(x) = 9x - 2 and g(x) = 2x², what is the value of f(4) - g(4)

Answer 1

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

Answer 2

9514 1404 393

Answer:

f(4) -g(4) = 2

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
