(-2,3), (0,1), (2,-4), (3,-1), (2,4) IS IT AN FUNCTION OR NOT

Mathematics

Answer: No

Explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.

In the relation shown here, notice that

the x-coordinate 2 appears twice.

In one case, 2 corresponds to -4 and in

the other case, 2 corresponds to -4.

Since the x-coordinate 2 corresponds to more than one

y-coordinate, no, this relation is not a function.

What is the inverse of f(x)=(x+6)2 for x≥–6 where function g is the inverse of function f?
alexdok [17]

Answer:

Sorry my mistake, it is actually worded as "f(x) =(x+6)^2"

Explanation:

y

=

(

x

+

6

)

2

with  

x

≥

−

6

, then

x

+

6

is positive, so

√

y

=

x

+

6

And  

x

=

√

y

−

6

for  

y

≥

0

So the inverse of  

f

is

g

(

x

)

=

√

x

−

6

for  

x

≥
