Answer:

f(-2) = 0

f(0) = -4

f(4) = 12

Step-by-step explanation:

Given the function f(x) = x^2 - 4, we must plug in the values substituting x for each of the answers.

f(-2) = (-2)^2 - 4

-2 times itself is a positive 4, therefore:

f(-2) = 4 - 4

f(-2) = 0

We do the same for each answer.

f(0) = (0)^2 - 4

f(0) = -4

f(4) = (4)^2 - 4

f(4) = 16 - 4

f(4) = 12

Expand 6(x-8)= x- (8) = help me
maksim [4K]

Answer:

x = 8

Step-by-step explanation:

6(x-8)= x- (8)

6x - 48=x - 8

6x- 48 + 48 = x - 8 + 48

6x = x + 40

6x - x = x + 40 - x

5x = 40

5x/5 = 40/5

x = 8

Hope it helps! :)

Answer:

2x = y

Step-by-step explanation:

As you can see in the table, y = 2x, this is proven by the fact that if you divide any value in the y of the table by 2 you will get its corresponding x value, proving that 2x = y is the function that is used to represent this table's value.
