I believe it is A 5w+8=w-12
Answer:
f(6) = 24
Step-by-step explanation:
f(x) = x^2 - 2x
Let x = 6
f(6) = 6^2 - 2(6)
= 36 - 12
= 24
Answer:
x=-2
y=4
Step-by-step explanation:
find y intercept let x=0
y=2(0)+4
y=4
find x intercept let y=0
0=2x+4
-4=2x
x=-2
WHO HAS THE ANSWER!! I DONT GET IT. PLEASE COMMENT THE ANSWER ON MY POST
If you begin with the basic equation of a vertical parabola: y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is
y + 2 = a (x + 3)^2. If we solve this for y, we get
y = a(x+3)^2 - 2. Thus, eliminate answers A and D. That leaves B, since B correctly shows (x+3)^2.
