Answer:
n = (-4)
Step-by-step explanation:
Firstly expand the bracket
;2[3(1 - n) -2(1+n)]
;2[ 3 - 3n - 2 - 2n ]
;2[ -5n + 1 ]
; -10n + 2
then go back to the question and substitute the bracket with the simplified form above,
; 7n - 10n + 2 = 14
; -3n = 14 - 2
; -3n = 12...then divide both sides by (-3)
;Hence... n = (-4)
if the point (9,26) lies on the graph y=f(x) then y= {inverse function} must contain (26,9)
The inverse of function:
A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. The inverse function is denoted by or if the function is represented by "f" or "F"
Given (x,y)=(9,26)
i.e.f(x)=y
⇒f(9)=26
inverse means swap x and y
i.e. y=
⇒ = y
⇒=9
Therefore, y= must contain (26,9).
Complete question: if the point (9,26) lies on the graph y=f(x), the graph of y= must contain what point
