Please please someone help me with this question

In the graph we can identify two local minimums, with values y = 0, and at the x-values:

x = -3 and x = 3.

For a function f(x), we define a local minimum on an interval (a, b) if for a value c ∈ (a, b), then:

f(c) ≤ f(x)   ∀ x ∈ (a, b)

a) On the image we can see two local minimums (the two lowest points on the graph). The values of the minimums are both 0.

b) The values of x where we have the minimums are:

x = -3 and x = 3.

If you want to learn more about minimums, you can read:

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
