Precalculus Chapter 1 Functions

State the domain and range of the function shown in set-builder notation.

• Domain: {x | x ∈ ℝ}, Range: {y | y ≥ 0}

• Domain: {x | x ≥ 0}, Range: {y | y ∈ ℝ}

• Domain: {x | x ∈ ℝ}, Range: {y | y ∈ ℝ}

• Domain: {x | x ≥ 0}, Range: {y | y ≥ 0}

Write the function to transform the parent function for f(x) = |x| when the graph is shifted left 7 units.

• f(x) = |x + 7|

• f(x) = |x − 7|

• f(x) = 7|x|

• f(x) = -7|x|

• f(x) = |x| + 7

• f(x) = |x| − 7
