Answer:
see the explanation and the attached figure
Explanation:
Part 1) Linear
we have
This is the equation of the line in slope intercept form
The slope is positive and equal to m=1
The y-intercept is b=3
As the value of x increases the value of y increases too
As the value of x decreases the value of y decreases too
therefore
The graph in the attached figure
Part 2) Quadratic function
