Question

What is the y-intercept of the graph of the function f(x) = x2 + 3x + 5?

Answer 1

(0, 5)

Explanation:

To solve for the y-intercept, plug in 0 for all x values and solve.

Answer 2

To find the y intercept you substitute 0 for x.

f(x)=(0)^2+3(0)+5
f(x)=5

So your y intercept

Is y=5 or (0,5)
