The x-intercepts are where the graph crosses the x-axis
To find the x-intercepts of an equation --> substitute in y = 0 and solve for x
The y-intercepts are where the graph crosses the y-axis
To find the y-intercepts of an equation --> substitute in x = 0 and solve for y
e.g. y = x2 + 4x + 3
1)To find the x-intercept
Let y=0, then x2 + 4x + 3 = 0.
Now, solve for x, which gives x= 1 , 3 [working excluded here]
So the x-intercept occurs at (1,0), (3,0)
2)To find the y-intercept
Let x=0, then y=3
So the y-intercept occurs at (0,3)
