No it isn’t because a function gives a y for every x

Answer:

No it isn't.

Step-by-step explanation:

A function gives just one  

y

for every  

x

.

In this case there will always be two  

y

's for every  

x

, because the reverse will be  

y

=

+

√

x

or

y

=

−

√

x

Example:  

x

=

4

→

y

=

−

2

or

y

=

+

2

Answer:

f(x) is shifted to the left 2 units of g(x)

f(x) will not be shifted vertically since we did not add anything to g(x)

Step-by-step explanation:

g(x) = x^2+2

f(x) = g(x+2)

When we shift  with h(x+c)  it is a horizontal shift

                  if c>0 it moves it left  c units

                  if c< 0 it moves it right c units

Since c is 2, this is shifted left 2 units

f(x) is shifted to the left 2 units of g(x)

When we shift  with h(x)+c  it is a vertical shift

                  if c>0 it moves it up  c units

                  if c< 0 it moves it down c units

f(x) will not be shifted vertically since we did not add anything to g(x)

Answer:

G(x)=2x+1 , vertical stretch by 2 units and shifted 1 unit up

Given :

Original function f(x)=x

To find :

Function G whose graph is a vertical stretch by 2  and move one unit up

We use the given function to for vertical stretch and shifting up

for Vertical stretch multiply the factor by f(x)

f(x) becomes  2f(x)

so the function becomes 2x

For moving up , we need to add the units at the end of the function

f(x)+1

2x+1

Hence, G(x)=2x+1
