Answer:
I imagine you aren't using calculus, so:
A: the leading term is 
, so it opens upwards.
B. First coordinate of the vertex is 
, the second coordinate we'll find by replacing the value: 
C. Quadratic formula or if you stare at the equation long enough you can rewrite the equation as 
. At this point the x intercepts are the zeroes of the function, or -6 and 2.
D. The y-intercept is the value of the function at 0, or the constant term: -12
E. The graph has a minimum since the curve opens upwards.
Answer:
a. y=7(x+0.5)^2+8.25
b. y=4(x+0.75)^2+0.75
c. the equation simplified is just f
d. f(f(x))=x^4+2x^3+4^2+3x+3
Hope tis helps
Answer:
Z = 4.5
Step-by-step explanation:
4z - 9 = 2z
4z -4z -9 = 2z -4z
-9 = -2z
-9 ÷2 = 2z ÷2
Z = 4.5
(18 + 36) - 6 =
54 - 6 =
48
