Answer:
Step-by-step explanation:
The functions, missing from the question are:
Required
Determine the domain
To get the domain, means we want to get the possible values of x.
(a)
Equate 3 - x to 0
Solve for x
From the calculated value of x above;
When x exceeds 3; f(x) = undefined
So: the domain is:
(b)
Equate 3x to 0
Solve for x
From the calculated value of x above;
When x falls below 0; f(x) = undefined
So: the domain is:
Answer:
A -- the curves that are not parabolas
Step-by-step explanation:
The inverse relation will only be a function if it passes the vertical line test: a vertical line cannot intersect the curve at more than one point.
A "half-parabola" can have an inverse function.
A parabola will have an inverse relation that is not a function. When x-values are repeated, as "goes through (5, 2) and goes through (5, -2)", the relation is not a function.
The graph that shows inverse functions is attached. A function and its inverse are mirror images of each other in the line y=x.
