Question

in the following relation, identify the domain and range. {(2.-4), (-2,4), (2,5), (5,-1), (-1,5)}

Answer 1

Domain is the first element of each set
Range is the second element of each set
Can you try now?

Answer 2

I understand how to get it, but i can't find the answer.

Answer 3

Write the first element of each set
{2, -2, 2, 5, -1}
remove the repeated elements
{2, -2, 5, -1}
Write in ascending order
{-2, -1, 2, 5}
This is the domain

Answer 4

thanks.

Answer 5

Can you do the same thing to find range?
here take the second element

Answer 6

i Still don't understand

Answer 7

Which part you have doubt?

Answer 8

Range.

Answer 9

I had the domain.

Answer 10

Please Read my posts again :)

Answer 11

How would the graphs of f(x) = 2x + 6 and g(x) = 2x + 3 compare if graphed on the same coordinate plane?

Answer 12

ignore that i put the wrong one.



Given f(x) = 3x + 2 and g(x) = -2x - 4, find h(x) = f(x) - g(x).

Answer 13

\[h(x)=f(x)-g(x)\]
plugin the values of f(x) and g(x)
\[h(x)=(3x+2)-(-2x-4)\]
Can you simplify this ?
