Step-by-step explanation & ANSWER BELOW IS IN BOLD:

Given the value of x, we can substitute the function rule.

Let's solve these problems together.

Note : Negative * Negative = Positive

If x= -4, then y = 11 because
y=-2*-4 + 3 = 8+3=11

If x = -2, then y = 7 because
y=-2*-2+3=4+3=7

If x = 0, then y = 3 because
y=-2*0+3=0+3=3

If x = 2, then y = -1 because
y=-2*2+3=-4+3=-1

Hope this helps :)

Have an awesome day!

Answer:

x y

-4 11

-2 7

0 3

2 -1

Explanation:

plug in x to solve for y.

when x = -4:

y = -2(-4)+3 = 8 + 3 = 11

y = 11

when x = -2:

y = -2(-2)+3 = 4 + 3 = 7

y = 7

when x = 0:

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

y = 3

when x = 2:

y = -2(2) + 3 = -4 + 3 = -1

y = -1
