• two

• no solutions

• all real numbers

What are the roots of this function?

• (-3, 0) & (1, 0)

• (0, -3) & (0, 1)

• (-1, -4) & (0, -3)

• (0, -1) & (-1, -4)

Without Desmos, choose the correct equation of this parabola?

• y = x² + 2x + 3

• y = -x² - 2x + 3

• y = x² + 2x - 3

• y = -x² - 2x - 3

Without using Desmos, identify the equation could match the graph.

• y = (x + 1)(x + 4)

• y = (x - 1)(x - 4)

• y = (x - 4)(x - 4)

• y = (x + 2.5)(x + 4)
