Answer:

i hope it will work

Step-by-step explanation:

f(x) = -5 x^2 + 2 x + 9

f(1)=-5(1)^2 +2(1) +9 = 6

similarly

f(2)=-5(2)^2 +2(2) +9 = -7

if its help-full then hit the stars and brain-list it

thanks

The graph of f(x) = x2 has been shifted into the form f(x) = (x - h)2 + k:

Nana76 [90]

The value of k would be 1. This is because the points (h, k) is the vertex and since k is the y-value of the vertex, we can see from the graph that it’s 1.

Angelina factored (x - 48 ) and wrote that it was equal to (x^2 - 4^2)^2(x^2 + 4^2). Use complete sentences to explain how you c

defon

(x^2 - 4^2)^2 = x^4 - 4^4
(x^4 - 4^4) (x^2 + 4^2) = x^2 - 4^6
The Angela's solution is wrong cause when you multiply you get a different answer.

Identify the value of a if y= ax+ 7x + 2 and the point (2, 12) is on the graph.

alexandr1967 [171]

Answer:

a=-2

So yep. ;)

Step-by-step explanation:

Alright, so, (2,12), 2 is the x and 12 is the y.

Stick them into the equation: $12=a*2+(7*2)+2$

Then, solve:

$12=a*2+14+2$

a = -2

So yes, they're on the graph.

Hope this helped! :)
