Question

can some one help me i need to know how to graph this f(x)=5x

Answer 1

plug in values for x, find corresponding y coordinates. plot the points on the graph.

Answer 2

that is what the graph will look like but it is not to scale. you have to plot the points properly

Answer 3

how did you get that ?i dont get it

Answer 4

ok how did you get the points?

Answer 5

k lets take 3 points for x.
-1,0,1

f(-1)=5(-1)=-5
f(0)=5(0)=0; this is the origin
f(1)=5(1)=5

so three points you can use are (-1,5), (0,0), (1,5). connecting those points with a line will show a graph similar to the one above

Answer 6

you can choose ANY points you want for x. because the domain is all real numbers

Answer 7

so you can choose any points

Answer 8

yep

Answer 9

as long as they are in the domain of the function.
for example if f(x) = 1/x; then x would not be allowed to equal zero. so you wouldn't use zero. because you can't divide by zerio.
