We have the parabola with equation y = 4x².
We have to determine the shape and direction of it.
If we compare it to the standard equation y = ax² + bx + c, we can see that a = 4, b = 0 and c = 0.
As the value of a is positive, the parabola will open upward.
The parameter has an absolute value greater than 1. This means that y increases "faster" relative to x that a parabola with a = 1.
This means that the parabola will be narrow about its line of symmetry which we call vertical strecth.
Answer:
Because a is positive the parabola opens upward.
Because a has an absolute value larger than 1 the parabola is narrow about its line of symmetry which we call vertical stretch.
Answer: 
Step-by-step explanation:
We know the rate for sales tax is:
This means Cindy has to pay for the bouquet of roses and the bouquet of daisies plus the 
of the value of each item.
So, we have to calculate the sales tax for both items:
Hence:
Yes because you are simply translating the shape and moving it and not changing the shape.
