Diego wrote \(f(x)=(x+2)(x-4)\) as an example of a function whose graph has \(x\)-intercepts at \(x=\text-4,2\). What was his mistake?
Write a possible equation for a polynomial whose graph has horizontal intercepts at \(x=2,\text-\frac12,\text-3\).
Which polynomial function’s graph is shown here?
Which expression is equivalent to \((3x + 2)(3x - 5)\)?
$6x - 3$
$9x^2 - 10$
$9x^2 -3x - 10$
$9x^2-9x - 10$
What is the value of \(6(x-2)(x-3)+4(x-2)(x-5)\) when \(x=\text-3\)?
Match each polynomial function with its leading coefficient.
