In the diagram, the curve y=9x2−9 cuts the x-axis at two points M and N. Find the coordinates of M and N.
Question
Solution 1
To find the points where the curve y = 9x^2 - 9 cuts the x-axis, we need to set y = 0 and solve for x. This is because the x-axis is defined by y = 0.
So, we have:
0 = 9x^2 - 9
We can simplify this equation by dividing through by 9:
0 = x^2 - 1
