Answer:
x = 11
Step-by-step explanation:
First, subtract 324 from both sides:
36x + 324 = 720
36x = 396
Divide each side by 36:
x = 11
So, the answer is x = 11
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=
as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
Answer:
Step-by-step explanation:
I'm very sure the answer would be (4, 64)
Answer:
D. There are no restrictions
Step-by-step explanation:
f(g(x)) = (x-2) + 5
= x - 2 + 5
= x+3
And since x + 3 is just a line, there are no domain restrictions.
