Question

Suppose f(x) = 2x + 5 and g(x) = -1/3x + 2. Find f(1)/g(3)

Please write answer step by step.
The answer should be 7 but I keep doing it wrong.

Answer 1

We have that
`f(1)=2(1)+5=2+5=7`, and
`g(3)= - (1)/(3(3)) +2=- (1)/(9) +2= (17)/(9)`

Now,
`(f(1))/(g(3)) = (7)/( (17)/(9) ) = (63)/(17)`

We can conclude that f(1)/g(3) is equal to
`(63)/(17)`; there is no way we can get 7 from this problem.

Answer 2

Given- f(x) = 2x + 5 g(x) = (-1/3)x + 2 , f(1)/g(3) = ? Solution- f(1) = 2*1 + 5 f(1) = 7 g(3) = (-1/3)*3 + 2 g(3) = -1 + 2 g(3) = 1 So, f(1)/g(3) = 7/1 f(1)/g(3) = 7
