Question

My post was deleted , it was, How is the graph of y = –2x2 – 4 different from the graph of y = –2x2?
It is shifted 4 units left.
It is shifted 4 units up.
It is shifted 4 units right.
It is shifted 4 units down.

Answer 1

i think the answer is "it is shifted 4 units down"

Answer 2

It will be shifted down by 4 so the last choice.

Answer 3

awee thanks guys yall are the best (:

Answer 4

you are welcome!

Answer 5

You're welcome!

Answer 6

What are the coordinates of the vertex of the graph? Is it a maximum or minimum?
(1, 0); minimum
(0, 1); maximum
(0, 1); minimum
(1, 0); maximum

Answer 7

the vertex is the peak of the curve which in this case is the highest so therefore can you tell the answer??

Answer 8

So 1,0 ?

Answer 9

it is 0,1 because since the first number is representing the x- coordinate and the second is representing the y-coordinate...

Answer 10

so 0,1 max ?

Answer 11

that is correct!

Answer 12

Thanks girl (:

Answer 13

you are welcome :)

Answer 14

Last one! Solve the equation using square roots.

5x2 – 45 = 0
–3, 3
–9, 9

no real number solutions

Answer 15

the attachment is a answer choice

Answer 16

!st step: the 45 that is subtracting crosses the equal sign to add to the zero.

2nd step: the five multiplying the x2 crosses to divide whatever is across the equal sign

3rd step: the square of the x crosses the square root of whatever is across the equal sign.
whenever you are taking square root you always bring + and -
