Answer: (-0.4, 6.8)
The graph is attached
Step-by-step explanation:
We can find the axis of symmetry using the formula x = -b/2a
x = - -4/2(-5)
x = 4/-10
x = 0.04
Substitute for x and calculate y
y = 
y = 6.8
The answer is A, you just have to plug it into the equation, but you missed up one the equation it's suppose to be P=10500(1.01)^x. To a power and multiplying are very different things
