Question

  1. explain what transformations are occurring compared to the parent functions.

f(x)=(x + 3)² −5 f(x) = 3|x − 4| f(x) = −x² + 8

  1. evaluate the following piecewise functions at x = 0 and x = 6.

(g(x)=\begin{cases}x + 4 & \text{if } x leq -2 \\x^2 + 7 & \text{if } -2 < x < 6 \\5x & \text{if } x geq 6end{cases}) (f(x)=\begin{cases}3x - 8 & \text{if } x < 1 \\- x + 7 & \text{if } x geq 1end{cases})

  1. graph the following piecewise functions.

(g(x)=\begin{cases}2 & \text{if } -3 < x leq -1 \\4 & \text{if } -1 < x leq 2 \\6 & \text{if } 2 < x leq 5end{cases}) (f(x)=\begin{cases}-2 & \text{if } x < -1 \\x + 3 & \text{if } -1 leq xend{cases}) (with two coordinate grid images for graphing)

Explanation:

Question 4: Analyze Transformations for Each Function
For \( f(x) = (x + 3)^2 - 5 \) (Parent: \( y = x^2 \))

Step1: Horizontal Shift

The term \( (x + 3) \) means a shift. For \( y = (x - h)^2 \), \( h = -3 \), so shift left 3 units.

Step2: Vertical Shift

The \( -5 \) at the end means shift down 5 units.

Step1: Vertical Stretch

The coefficient \( 3 \) (greater than 1) vertically stretches the graph by a factor of 3.

Step2: Horizontal Shift

The \( (x - 4) \) means shift right 4 units (since \( h = 4 \) in \( y = |x - h| \)).

Step1: Reflection

The negative sign in front of \( x^2 \) reflects the graph over the x - axis.

Step2: Vertical Shift

The \( +8 \) at the end means shift up 8 units.

Answer:

Shift left 3 units, shift down 5 units.

For \( f(x) = 3|x - 4| \) (Parent: \( y = |x| \))
