Quadratics: Match quadratic functions and graphs

Identify quadratic functions from their graphs and find key features of their graphs (intercepts, #vertex, axis o symmetry, maximum value) from the equation. Based on Common cor...

The graph of f(x) = −2x² + 4x − 1 is a parabola opening

A quadratic function has a maximum value of 5. Which could be the equation of the function?

f(x) = −2(x − 5)² − 2 f(x) = −(x + 1)² + 5 f(x) = (x − 2)² + 5
What are the x-intercepts of the graph of f(x) = x² − 3x − 10?
