Answer:
c) f(x)=3x+1
Step-by-step explanation:
the graph of this function, g(x), is y=3x-1, we know this because the slope is 3 and the y intercept is -1.
finding slope:
subtract the y values and x values and then divide.
y2-y1/x2-x1=2+1/1-0
=3/1
slope=3
finding the y intercept:
more of a visual task, find where the line intersects on the y axis. in this case, it is at -1
plug it in:
next all you have to do is plug this into slope intercept form (y=mx+b), where m is slope and b is y intercept.
y=3x-1
making f(x) from g(x):
all you have to do is add 2 to the y intercept because the question says f(x) is 2 units above g(x).
y=3x-1+2
y=3x+1
hope this helps!
