Answer:
-2 = n
Step-by-step explanation:
-3 + 4n = 4n + 3 + 3n
-3 + 4n = 7n + 3 [Combine like-terms]
-7n -7n
________________
-3 - 3n = 3
+3 +3
________________
-3n = 6
n = -2

The general form for this parabola ix x^2 = 4ay where the focus is (0,2)
a = 2 so we have:-
x^2 = 4(2)y
y = (1/8) x^2 is the answer.
F(x) = -x^2 + 3x + 8
f'(x) = -2x + 3
when f(x) is increasing f'(x) > 0
-2x + 3 > 0
-2x > -3
x < 3/2 or 1.5
So the required interval is (-infinity,1.5).The first choice.
