Answer:
Alright same for here to find the inverse, interchange the variables and solve for y
f - 1 (x) = - 2 (1 + x)/2 + x Hope this help's :)
Step-by-step explanation:
The domain is the value of x. In this case, -3≤x≤7
the range is the value of y. in this case, -1≤y≤9
this is not a function, because the same x value has two corresponding y values. For example, when x=5, y=0 or y=8
It IS a function if every x value has only one corresponding y value.
3 + 3 + 1 = 7
3 + 3 are the double ones
+1
=7
7/8*8/9 = (7*8)/(8*9)
Since we have an 8 both above and below, we can erase it, and so the answer is 7/9
