G because she need to sell 20 vases because the cost is 450 and if you divide it by 23 for the price the vases will be sold for it comes to 19.57 and you can't sell .57 of a vase you have to round up to make more than the money spent
4 - 2(x + 3) = 5
4 - 2x - 6 = 5
-2x - 2 = 5
-2x = 5 + 2
-2x = 7
x = -7/2 or = -3 1/2
The inverse of the function is f(x) =
+ 8
In order to find the inverse of any function, start by switching the f(x) and x. Then solve for the new f(x). The result will be the inverse function. The work is below for you.
f(x) =
----> Switch f(x) and x
x =
----> Cube both sides
= f(x) - 8 ----> Add 8 to both sides
f(x) =
+ 8
Answer:
(d) f(x) = -x²
Step-by-step explanation:
For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...
f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)
f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)
Of the offered answer choices, the only one with a vertex at the origin is ...
f(x) = -x² . . . . . a=-1
