You can put this solution on YOUR website! Plot the graphs of the following functions. Scan the graphs and post them to the Facilitator along with your response.
Justify your answer.
1.f(x) = 5x
2.f(x) = 4x+2
3.f(x) = (1/3)x
---------------
These are linear, straight lines. To graph them you need only 2 points.
1.f(x) = 5x
Use y for f(x)
y = 5x
Pick 2 values for x, then solve for y
at x = 0, y = 0 --> (0,0) 1st point
at x = 2, y = 10 --> (2,10) 2nd point
Plot the 2 points, draw a line thru them.
------------------
#2 and #3 are similar.
