Please help me with this question. I am very confused.
Oksanka [162]
I think u do the ones in the parenthesis first bc of PEMDAS since it's both negative it become positive and u can cross out both the 2's and that leaves u with 1/7 and then u just times 1/7 with 8 and then u get 8/7

hoped this helped! :)

Determine the vertex of the function f(x) = 2(x - 5)2 + 8.
Pachacha [2.7K]
Solve for x, which can be done by moving x to the other side.
2(x-5)^2+8

So, x = 5

The y value is the number at the end and we can see that it is positive 8.

y = 8

Write it out as a coordinate pair and you would get (5,8) or answer choice D
