Answer:
Step-by-step explanation:
We are given the function:
And that:
And we want to determine the value of <em>c</em>.
Recall that by definition of inverse functions:
So, since f⁻¹(5) = -1, then f(-1) = 5.
Substitute:
Simplify:
Combine like terms:
And divide. Hence:
In conclusion, the value of <em>c</em> is -2.

Answer:
B represents a function.
Step-by-step explanation:
Recall these characteristics of a "function:"
Only one y-value can be associated with each x-value.
Thus, A could not represent a function because there are two points with x = 1 and two different y-values: (1, 1) and (1, -2).
B represents a function because for each input (x-value) there is one and only one y-value associated.
C not a function: (2, 3) and (2, -3) have two different y-values associated with one x-value (2).
D not a function: (-3, 4) and (-3, -4) (see A and C, above)
A=4
The work behind it
-11a+33= -11
-33 -33
-11a=-44
Divide both sides by -11
-44/-11=a
A=4
