In this lesson, we will learn how to identify features of quadratic functions, such as its vertex, extrema, axis of symmetry, domain, and range.
Q1:
Find the coordinates of the vertex of the function 𝑓(𝑥)=−7𝑥+7𝑥+5.
Q2:
Find the coordinates of the vertex of the graph of 𝑓(𝑥)=𝑥−6𝑥−4. State the value of the function at the vertex and determine whether it is a maximum or minimum value.
Q3:
Find the axis of symmetry of the graph of 𝑓(𝑥)=4𝑥+4𝑥−3.
