M1T1L4 Forms of Quadratics Practice

Answer explanation

Because the leading coefficient, -3, is negative, the graph is concave down.

Which function matches the graph?

Answer explanation

These functions are given in the factored form, so use the x-intercepts to determine the correct function.

Answer explanation

Remember to change the sign of the values in the factors to find the x-intercepts.

Which function matches the graph?

Answer explanation

These functions are given in the standard form. Use the leading coefficient and the y-intercept to determine the correct function.

• Standard

• Factored

• Vertex

Which function matches the graph?

Answer explanation

These functions are given the vertex form. Use the vertex and concavity of the graph to determine the correct function.

Which function matches the graph?

Answer explanation

These functions are given in the factored form. Use the concavity and the x-intercepts of the graph to match.

Answer explanation

Remember to change the sign of the value inside the parenthesis to get the x-coordinate of the vertex, keep the sign for the y-coordinate.
