Question 72661
using number lines from-5 to 15 draw mapping diagrams to illustrate the functions x arrow 3x + 2 and x arrow4x-3
-----------------
That notation means y=3x+2 and y=4x-3
"from -5 to 15" means the domain and the range are limited to those numbers.
---------
To graph y=3x+2 plot the points (0,2),(1,5) and draw a line thru them.
To graph y=4x-3 plot the points (0,-3),(1,1) and draw a line thru them.
---------
{{{graph(400,300,-5,15,-5,15, 3x+2,4x-3)}}}
