Question

Can someone help me find the maximum or minimum value?

Answer 1

Answer:

(c) Minimum value is -16.

Step-by-step explanation:

This will have a minimum value because the leading coefficient is positive.

We can find the minimum value by converting the function to vertex form:

f(x) = x^2 + 4x - 12

f(x) = (x + 2)^2 - 4 - 12

f(x) = (x + 2)^2 - 16.

The minimum value is -16.

So when you draw the graph the turning point is at (-2, -16).
