# 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]}
