Question

1. f(x)=3x - 8; find f(4) - f(-3)

Explanation:

Step1: Calculate \( f(4) \)

Substitute \( x = 4 \) into \( f(x)=3x - 8 \):
\( f(4)=3(4)-8 = 12 - 8 = 4 \)

Step2: Calculate \( f(-3) \)

Substitute \( x = -3 \) into \( f(x)=3x - 8 \):
\( f(-3)=3(-3)-8 = -9 - 8 = -17 \)

Step3: Find \( f(4)-f(-3) \)

Substitute the values of \( f(4) \) and \( f(-3) \):
\( f(4)-f(-3)=4 - (-17)=4 + 17 = 21 \)

Answer:

21
