Answer:
x=3
Step-by-step explanation:
By vertical line test, x=3 fails because more than 2 points have the same x value. Functions must pass the vertical line test.
I made a number line and drew it out -6,-5,-4,-3,-2,-1,0,1,2 and i counted how many i had to move over to get to 2 from -6 and i got 8
7,14,21,28,35
Multiply 7 by 1-5
90% of 100 = 0.9 x 100 = 90
