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.

<h3>What is percentage of a number?</h3>Percentage of a number is the part of the whole number which is expressed in the fraction of hundredth. It is represented with "%" symbol.
35% of salt is in feta cheese. The percentage of salt is in that 350 g cheese has to be found out.
Let suppose there is x grams of slat in feta cheese of 350 g. Thus, the amount of salt (35% of 350) is,
Thus, the amount of salt is in the 350 g of feta cheese, when there is 35% of salt is in cheese, is 122.5 grams.
