Question

is maximum or minimum?what is the value?what is the axis of symmetry is x =

Answer 1

Answer:

• The minimum value of the graph is y=-8.

,

• The axis of symmetry is x=2

Explanation:

On examining Josie's steps, she did not make a mistake.

In the function, f(x):

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

The coefficient of x² is positive, therefore, the graph has a minimum.

From the vertex, (2,-8):

• The minimum value of the graph is y=-8.

,

• The axis of symmetry is x=2
