A vertical parabola is: y = a(x-h)² + k
where (h,k) is the vertex and "a" is the vertical stretch/shrink.
A negative sign in front of the "a" represents a reflection over the x-axis.
y = a(x-0)² + 0
y = a(x)²
Answer: B (y = 3x²)
If u can find it i can’t sorry lol
Answer:

Step-by-step explanation:

Alright here I go:
9.98 * 10^6 in standard form is 9,980,000
7.3 * 10^7 in standard form is 73,000,000
73,000,000 subtracted by 9,980,000 is 63020000.
63020000 in scientific notation is 6.302 * 10^7
Hope I helped!
First: 13 x 8 = 104
Second: 8/2 = 4
Third: 104 + 4 = 108
Your answer is 108
