Question

For g = {(-5,2).(-4,-1) .(3,-8).(-2,0),(4,-9 ) } find the indicated value
13) g(-4) =
14) g( 4 ) =
15) g( 3) =
16 ) g(-5) =


how do i solve this it confuses me so much, please someone help​

Answer 1

Remember that g(x)=y
g(-4) is just another way of asking, “for what value of y does x=-4?”
Applying this rule to all of these problems gives you

g(-4)=-1
g(4)=-9
g(3)=-8
And g(-5)=2
Remember a coordinate point is of the form (x,y) so when x=-4, y=-1. When x=4, y=-9, when x=3, y=-8, and when x=-5, y=2. The answers are on the top. I’m just trying to explain how you would tackle these type of problems in the future. Hope this helps!!! Dm me if you have other questions :)
