Question

can someone help me with a math problem please

Answer 1

y = -2x^2 + 2x +2 convert into vertex form is y = -2(x + 1/2)^2 + 5/2 , when x = 6 , y = -58 .
y = -2x^2 + 2x + 2
y = -2(x + 1/2)^2 + 1/2 + 2
y = -2(x + 1/2)^2 + 5/2
when x = 6
y = -2*6^2 + 2*6 + 2
y = -72 + 14
y = -58

Answer 2

is this right ?

Answer 4

Let me check.

Answer 5

ok

Answer 6

y = -2x^2 + 2x + 2. If x = 6, we plug that in.
y = -2(6)^2 + 2(6) + 2.
y = -12^2 + 12 + 2.
y = -144 + 12 + 2.
y = -144 + 14.
y = -130. - That's what I got.

Answer 7

ok umm

Answer 8

well let me double check

Answer 9

Well I suppose if you did the order of operations I guess you would be correct, but I'm pretty sure you would multiply 2x together first before messing with the exponent.
