What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(−
2 answers:
Solution:
1. The given function is
f(x) = 2 x
it is equation of line passing through origin having slope 2 and the line passes through first and third quadrant.
Domain= All Real numbers, Range = All Real Numbers
2. Now , when x is replaced by (-12 x), we get
f(-12 x)= 2 × (-12 x)
Let f(-12 x)= f(z)= -24 x
it is equation of line passing through origin having slope -24 and the line passes through second and fourth quadrant.
Domain= All Real numbers, Range = All Real Numbers
Relation between the two function i.e between 1 and 2 is
→Slope of line 2 = Slope of line 1 × (-12)
→ The function 2 i.e f(z)= -24 x shifts in left Direction.
The function 1 is dilated by factor of (-12) to get function 2.

John's gross monthly salary is $2000.
John receives a 15% raise in his salary.
So first we have to find 15% of $2000.
15% of 2000 =
=
=
=
John's salary including the raise = $ = $2300.
Now 30% of his monthly paycheck withheld for taxes.
30% of 2300 =
=
=
=
So the amount of tax deducted = $690.
John's net monthly income = $ = $1610.
So we have got the required answer.
