Answer:
The vertex is at (2,1)
Step-by-step explanation:
The vertex form of a quadratic is
y = a(x-h)^2 +k where (h,k) is the vertex
f(x) = 3(x - 2)^2 + 1.
The vertex is at (2,1)
Answer:
9
Step-by-step explanation:
Use PEMDAS to solve it.
2 3 - (8-4) + 5 =
First: 2 3 - (4) + 5 =
Second: solve the 2 to the power of 3 exponent
2×2×2=8 (2×2=4 then 4×2=8)
So, 8 - 4 + 5 =
Third: 4 + 5 =
Last: 9
Th answer to number 1 is B. The answer to number 2 is C. The answer to number 3 is A. The answer to number 4 is the first graph {(1,80),(2,240),(3,720),(4,2160)}
