Answer:
x y
-4 11
-2 7
0 3
2 -1
Step-by-step 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
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 [tex]y=-2*-4 + 3 = 8+3=11[/tex]
If x = -2, then y = 7 because [tex]y=-2*-2+3=4+3=7[/tex]
If x = 0, then y = 3 because [tex]y=-2*0+3=0+3=3[/tex]
If x = 2, then y = -1 because [tex]y=-2*2+3=-4+3=-1[/tex]
Hope this helps :)
