topic 6 lesson 1: practice
level 2: fill in the blanks/answer the questions

1. write the general form for the vertex form of a quadratic.
2. a complex number is a number that can be written in the form ____________, where a and b are____________.

Explanation:

Step1: Recall vertex - form of quadratic

The general vertex - form of a quadratic function is $y=a(x - h)^2+k$, where $(h,k)$ is the vertex of the parabola and $a
eq0$.

Step2: Recall form of complex number

A complex number is written in the form $a + bi$, where $a$ and $b$ are real numbers.

Answer:

1. $y=a(x - h)^2+k$
2. $a + bi$, real numbers
