Answer:
now i know my abc's
Step-by-step explanation:
Is would be a I think because if you times those to numbers you get 20
f(x) = x^2 + 6x - 7
y = x^2 + 6x - 7
y = (x - 1)(x + 7)
x + 7 = 0
x = -7
x - 1 = 0
x = 1
The x-intercepts are -7 and 1.
Since the leading coefficient is a positive, the graph will point upwards.
So, the graph of the function is D.
I think it will be set up as 2000(.051)^3
