2-111.

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

 a. f(1) b. f(0) c. f(−3) d. f(1.5) Hint (a):Substitute 1 for every x.Answer (a):f(1) = −6 Answer (d):f(1.5) = Undefined. You can't divide by 0. e. What value of x would make f(x) = 4?
• $4=\frac{6}{2x-3}$

• x = 2.25
