Question

evaluate the function at the given values. f(x)=4x - 4 a. f(5) b. f(-1/2) c. f(0) a. f(5)=□

Explanation:

Step1: Substitute x = 5 into f(x)

$f(5)=4\times5 - 4$

Step2: Calculate the result

$f(5)=20 - 4=16$

Step3: Substitute x = -1/2 into f(x)

$f(-\frac{1}{2})=4\times(-\frac{1}{2})-4$

Step4: Calculate the result

$f(-\frac{1}{2})=-2 - 4=-6$

Step5: Substitute x = 0 into f(x)

$f(0)=4\times0 - 4$

Step6: Calculate the result

$f(0)=0 - 4=-4$

Answer:

a. $16$
b. $-6$
c. $-4$
