Question

find f(0) when f(x) = x² + 3x - 5.
a. -5
b. 25
c. 0
d. 5

Explanation:

Step1: Substitute x = 0 into f(x)

To find \( f(0) \), we substitute \( x = 0 \) into the function \( f(x)=x^{2}+3x - 5 \). So we get \( f(0)=0^{2}+3\times0 - 5 \).

Step2: Calculate the value

First, calculate \( 0^{2}=0 \) and \( 3\times0 = 0 \). Then substitute these values back into the expression: \( f(0)=0 + 0-5=-5 \).

Answer:

A. -5
