Answer:
Step-by-step explanation:
Subtract the equations we get
-3y=-3
y=1
x=3-1=2
x=2
F(x)=3x²+2 . The intersection of this parabola with y-axis is 2 [f(0)=2]
If you want to stretch it vertically by a factor of 4. that means instead of 2 previously calculated the total stretch should be 2.4 =8 [f(0)=8]
The stretched equation becomes(x) = 3x² + 8
They with owe $44.73 each
239.66+85.43+32.75=357.86/8=44.73
