Answer:
see attached
Step-by-step explanation:
To find the inverse function, solve ...
x = f(y)
x = (y^7)/7 -4 . . . . . . . use the definition of f(x)
x +4 = (y^7)/7 . . . . . . add 4
7(x +4) = y^7 . . . . . . multiply by 7
(7(x +4))^(1/7) = y . . take the 7th root
The inverse function is the one shown in the attachment.
Answer:
-3 Or 3 it could be any one of them
Step-by-step explanation:
-3 or 3
Rise/run so an
Answer:
no
Step-by-step explanation:
Proportional must go through (0,0)
0 = 2(0) +7
0 = 7
This is not true so this is not proportional
Answer:
y = 3x -13
Step-by-step explanation:
y = 3x + 7
-1 = 3(4) + b
-1 = 12 + b
-13 = b
y = 3x -13
