Question

If f(x) = 7 + 4x and g(x)=1/2x, what is the value of {f/g}(5)?

Answer 1

Answer: 270

Step-by-step explanation:

Given: $f(x)=7+4x$ and $g(x)=\dfrac{1}{2x}$

Then, the rational function (f/g) is given by :-

$(f/g)(x)=\dfrac{f(x)}{g(x)}\\\\\Rightarrow\ (f/g)(x)=\dfrac{7+4x}{\dfrac{1}{2x}}\\\\={2x(7+4x)}$

Now, the value of (f/g) is given by :-

$(f/g)(5)=2(5)(7+4(5))=270$

Hence, the value of (f/g) (5) = 270.
