If f(x) = 7 + 4x and g(x) = 1/2x, what is the value of (f/g)(5)?
Solution:
Given, functions are
f(x) = 7 + 4x, g(x) = 1/2x
We have to find (f/g)(5).
Now, (f/g)(x) = (7 + 4x)/(1/2x)
= (7 + 4x)(2x)
= 14x + 8x2
Put x = 5 in the above expression,
(f/g)(5) = 14(5) + 8(5)2
= 70 + 8(25)
= 70 + 200
= 270
Therefore, (f/g)(5) is 270.
If f(x) = 7 + 4x and g(x) = 1/2x, what is the value of (f/g)(5)?
Summary:
If f(x) = 7 + 4x and g(x) = 1/2x, the value of (f/g)(5) is 270.
