Answer: (0, 5)
Explanation:
To find the y-intercept, we will substitute 0 for x into the equation given. This means we will find (0, y), which is the y-intercept.
Given:
f(x) = x² + 3x + 5
Substiute:
f(0) = (0)² + 3(0) + 5
Multiply:
f(0) = 5
Based on this, the y-intercept is (0, 5). We can also see this when we graph the function. See attached.
