Answer:
f(a)=2a+4
Step-by-step explanation:
1. multiply 2×a, which equals to 2a
2. then multiply 2×3, which equals to 6
3. then you'll get f(a)=2a+6-2
4. subtract 6 and 2
5. once that is done your answer will be f(a)=2a+4

Answer:
C) (1, 12)
Step-by-step explanation:
You can rewrite the equation in vertex form:
y = -4(x^2 -2x) +8 . . . . . factor the leading coefficient from the first two terms
y = -4(x^2 -2x +1) +8 +4 . . . . . add the square of half the x-coefficient inside parentheses (-4)((-2/2)^2) and its opposite outside parentheses (-(-4)).
Now, the equation can be written in vertex form.
y = a(x -h)^2 +k . . . . . . . . . has vertex (h, k)
y = -4(x -1)^2 +12 . . . . . . . . has vertex (1, 12)
______
<em>Comment on the problem</em>
The typewritten form of the equation seems to have a missing leading minus sign. Its vertex is (-1, 4), so "none of the above."
