Question

the time it takes natalie to replace \\(x\\) cell phone screens is given by the equation \\(t = 1 + 3x\\), where \\(t\\) gives the time in hours. how many hours would it take natalie to replace 8 screens?

a) 25
b) 4
c) 22
d) 24

question 2 (5 points)
given the function \\(f(x) = \sqrt{x}\\) and the function \\(g(x) = \sqrt{x} - 4\\), what does the -4 do to the graph of \\(f(x)\\) to get the graph of \\(g(x)\\)?

a) translates the graph to the left by 4 units
b) translates the graph 4 units downward
c) translates the graph to the right by 4 units
d) translates the graph 4 units upward

Explanation:

Evaluate the linear model for Question 1

Analyze the function transformation for Question 2

$$
LATEXBLOCK1
$$

Subtracting 4 from the output of a function shifts its graph vertically downward by 4 units.

Answer:

Question 1

• (A) 25 (Correct answer)
• (B) 4
• (C) 22
• (D) 24

Question 2

• (A) Translates the graph to the left by 4 units
• (B) Translates the graph 4 units downward (Correct answer)
• (C) Translates the graph to the right by 4 units
• (D) Translates the graph 4 units upward
