In this lesson, we will learn how to define and evaluate functions and find the roots and the maximum or minimum of quadratic functions.
Students will be able to
Q1:
If 𝑓(𝑥)=5𝑥+7, evaluate 𝑓(−1).
Q2:
Given that 𝑓(𝑥)=𝑥+3 and 𝑔(𝑥)=−2𝑥+3, find the value of 𝑓(1)+𝑔(2).
Q3:
If 𝑓(𝑥)=2𝑥+4 and 𝑔(𝑥)=2−𝑥, calculate 𝑓(−1)𝑔(0).
