This worksheet is about matching curves to equations.

**Example**

Match the curve with its equation:

y = x^{3} −2 OR y = x^{3} +x^{2 }OR y = x^{2} - 2

**Answer**

Look at the curve. It has a cubic shape so will definitely have an x^{3} in the equation.

Then look at what happens when x = 0.

It passes through (0,0), so the equation cannot be y = x^{3} −2

The equation is **y = x ^{3} +x^{2}**

(check that this passes through (-1, 0). When x = -1, y = -1 + 1 = 0
