Transforming the graph of a function by shrinking or stretchingGraph (a)

ANSWER

EXPLANATION

If g(x) is the transformation of f(x) as follows,

g(x)=f(ax)

Then g(x) is a horizontal compression (if a > 1) or stretch (if a < 1) of f(x). The rule to map each point is,

(x,y)\to(x/a,y)

In this case, this is a stretch so the point (-2, 2) maps to the point (-4, 2) and the origin is the same. Join these two points with a line and we get the graph of f(¹/₂x).

Solve - 2( x+ 4) = 12
Zolol [24]

Step-by-step explanation:

2(x+4) = 12

or, 2x + 8 = 12

or, 2x = 12-8

or, 2x = 4

or, x = 4÷2

hence, x = 2
