Answer: OPTION D.
Step-by-step explanation:
The vertex form of a quadratic function is:

Where (h, k) is the vertex of the parabola and "a" is the coefficient of the squared in the parabola's equation.
We know that the vertex of this parabola is at (5,5) and we also know that when the x-value is 6, the y-value is -1.
Then we can substitute values into
and solve for "a". This is:
Step-by-step explanation:
f(x) = y ( true statement)
y = -1/5x + 3
To find the inverse of any given function we switch the X and Y
X = -1/5y + 3
isolate y so:
x-3 = -1/5y
Multiply both sides by -5
-5(x-3) = y
-5x + 15 = y
Fifth term / second term = a1r^4 / a1r = r^3 = 768 / -12 = -64
so r = -4 and first term a1 = -12/-4 = 3
answer is 3*(-4)^(n-1)
Its C
To find 8x397, I used the stack method.
a.) 397
<u> x 8 </u>
3176
b.) This method works best because it's easy to do, and the factors aren't too big to multiply by hand, unless it was like a billion times a million. But in this case, it's not, so it's perfectly fine to use the stack method.
I hope this helps and have a good night! :D
