Question

Identify the minimum value of the function y = x2 + 6x + 9. 9 −3 0 1

Answer 1

0

Explanation:

Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain. You will get 0.

Answer 2

0.

Explanation:

y = x^2 + 6x + 9

Convert to vertex form:

y = (x + 3)^2 - 9 + 9

y = (x + 3)^2

So the minimum value is when x = -3:

y = (-3 + 3)^2 = 0.
