I am given two different equations and I have to graph both of them now I am quite unsure as to how to graph but I first worked out the problems like this:
f(x) = -3x+7 and this is how I worked it out. since they didn't give me a number for x I just used (2)
so my problem goes like this:
f(2)= -3(2)+7
f(2) = -6 + 7
f(2) = 1
so my points for this problem would be (2,1)
now my main question for this is would this be right just for me to put any number in for x so I can solve or should I have solved it another way?
Thanks.
