Answer:
f - 1 (x) = - x6 - 76
Step-by-step explanation:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=−x6−76 f - 1 ( x ) = - x 6 - 7 6 is the inverse of f(x)=−6x−7 f ( x ) = - 6 x - 7 .
Answer:
The sixteen people to March in the sportsmanship parade
Step-by-step explanation:
A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population.

Equation :
This parabola is facing downwards and highest point of the parabola is it's vertex.
Highest point is (-2,2)
so the vertex is (-2,2)
The graph is passing through (-1,0)
Equation in vertex form is


Substitute back in Equation

the graph has two x intercepts -1 and -3
that means (x+1) and (x+3) are the factors
multiply factors to get the equation in standard form

-2x^2-8x-6=0

Answer:
<u>$239.68</u>
Step-by-step explanation:
<u>Given</u>
- Cost = $224
- Sales Tax = 7%
<u>Solving</u>
- Cost w/ Tax = Cost (1 + Tax)
- Cost w/ Tax = 224 (1 + 0.07)
- Cost w/ Tax = 224 * 1.07
- Cost w/ Tax = <u>$239.68</u>
