Question 1 of 5
A graph in the -plane represents the function . Which expression is equivalent to this function and shows its -intercept directly?
Explanation
Expand the product: . In standard form, the constant term is the -intercept, so this form shows directly that the graph crosses the -axis at .
Concept summary
To rewrite a factored quadratic in standard form, use distribution and combine like terms. The constant term in gives the -intercept.
