2-111.

Use the function $f(x) = \frac { 6 } { 2 x - 3 }$ to calculate the value of each expression below.

1. $f(1)$

Substitute $1$ for every $x$.

$f(1) = −6$

1. $f(0)$

1. $f(−3)$

1. $f(1.5)$

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

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

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

$x = 2.25$
