Answer:

a) 8

b) -4

c) 3x² - 4x + 8

d) 20

e) 28

Step-by-step explanation:

a) (-2)² + 4 = 8

b) 8 + [4(-2) - 4] = 8 + (-8 - 4) = 8 + (-12) = -4

c) 3(x² + 4) = 3x² + 12

3x² + 12 - (4x - 4) = 3x² - 4x + 8

d) g(2) = 4 4² + 4 = 20

e) f(2) = 8 4(8) - 4 = 28

Plot a graph of the line y = x - 3. Help please ASAP!

eduard

Step-by-step explanation:

An easy way to plot two points and connect them with line

Point 1

x = 0, this gives us y = - 3
So (0, - 3)

Point 2

x = 3, this gives us y = 0
So (3, 0)

Now plot these two points to get the line
