5-8.

For the function$f ( x ) = \frac { 6 } { 2 x - 3 }$, find the value of each expression below. Homework Help ✎

1. f (1)

Substitute 1 for every x.

f(1) = −6

2. f (0)

3. f (−3)

4. f (1.5)

f(1.5) = Undefined. You can't divide by 0.

5. What value of x would make f(x) = 4?

$4=\frac{6}{2\textit{x}-3}$

x = 2.25
