Question

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

Answer 1

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

Answer 2

We have that $f(1)=2(1)+5=2+5=7$, and $g(3)= - \frac{1}{3(3)} +2=- \frac{1}{9} +2= \frac{17}{9}$

Now, $\frac{f(1)}{g(3)} = \frac{7}{ \frac{17}{9} } = \frac{63}{17}$

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