Question #f986a
1 Answer
graph{x^2 [-40, 40, -20, 20]}
graph{x+6 [-80, 80, -40, 40]}
Explanation:
Let's graph these one by one.
You can graph this by subbing in points:
when
when
when
Or, you can memorise what this graph looks like. It has a vertex at the origin, with two arms branching upwards on either side of the y-axis:
graph{x^2 [-40, 40, -20, 20]}
(Note:
To graph this one, you need to find the x- and y-intercepts:
x-intercept (when y=0):
So the graph cuts the x-axis at
y-intercept (when x=0):
So the graph cuts the y-axis at
You then plot these two points on a graph and draw a straight line that goes through both points:
graph{x+6 [-80, 80, -40, 40]}
