Given: f(x) =
x+5
and g(x) = x - 2.
What are the restrictions of the domain of f(g(x))?
X = -5
x= -3
X = 2
There are no restrictions.
DONE

Good Job you answered your own question

no restriction

Step-by-step explanation:

f(g(x)) means put g(x) equation into "x" in f(x) equation

so it is f(x-2+5)

f(x+3)

x+3=0

x=-3

sub back into x+5 you get 2

sub back into x-2 you get -5

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
