SOLUTION: graph f(x)=|x-3|+2 include all intercepts and the vertex. I am not sure how to do the absolute value signs on here but they should go where the parentheses are.
Thank you

You can put this solution on YOUR website! graph f(x)=|x-3|+2 include all intercepts and the vertex.
:
To find the y intercept, let x=0 and solve for y:
f(x)=y=|x-3|+2
y=|0-3|+2
y=|-3|+2
y=3+2
y=5 Plot (0,5) the y-intercept.
:
To find the x-intercept, let y=0 and solve for x:
0=|x-3|+2
-2=|x-3|+2-2
-2=|x-3| An absolute value is always positive, therefore there are no x-intercepts.
:
To find the vertex:
(x-3)+2=-(x-3)+2
x-3+2=-x+3+2
x-1=-x+5
x-1+1=-x+5+1
x=-x+6
x+x=x-x+6
2x=6
2x/2=6/2
x=3 This is the x coordinate of the vertex.
y=|3-3|+2
y=|0|+2
y=2
The vertex is (3,2) Plot that.
Since there were no x-intercepts, you may want to let x= a couple of other numbers to get a couple of more points.
Happy Calculating!!!
