Question

The function f is defined by f(x)= 7+x/-6+3x Find f(4a)

Answer 1

Answer:

$\frac{7 +4a}{-6 + 12a}$

Step-by-step explanation:

Given: f(x) = $\frac{7 + x}{-6 + 3x}$

Now to determine f(4a) substitute 4a in the place of x.

⇒ f(4a) = $\frac{7 + 4a}{-6 + 3(4a)}$

⇒ f(4a) = $\frac{7 + 4a}{-6 + 12a}$
