- 1. Multiple Choice
f(x)=4x+50f(x)=4x+54f(x)=50x+4f(x)=54x+4 - 2. Multiple ChoiceThis function represents the value, in dollars, of a particular model of car, where x represents the number of miles driven:
f(x)=−50x+25,000
What is the average rate of change in the value of the car in dollars per mile?-25,000-505025,000 - 3. Multiple ChoiceMr. Yair’s class is collecting aluminum cans to raise money for a trip. The rates are shown.
$0.75 per pound for a collection weighing 10 pounds or less
$1.25 per pound for a collection weighing more than 10 pounds
What are the domain and range for a collection that weighs more than 10 pounds?{x|x<10}; {y|y<$12.50}{x|x<10}; {y|y<$7.50}{x|x>10}; {y|y>$12.50}{x|x>10}; {y|y>$7.50} - 4. Multiple ChoiceThe amount Keisha can earn at her job is shown.
$7 per hour up to 40 hours per week
1.5 times the hourly wage for every hour over 40
Which piecewise-defined function best represents Keisha’s weekly pay, P(h), where h represents the hours worked?P(h)= 7h, 0≤h≤40
P(h)=10.5h+140, h≥40P(h)=7h, 0<h<40
P(h)=10.5h+140, h≥40P(h)=7h, 0<h<40
P(h)= 10.5h−140, h>40P(h)= 7h, 0≤h≤40
P(h)= 10.5h−140, h>40 - 5. Multiple ChoiceThe piecewise-defined function f(x) is shown.
f(x)=x+2, x≤0
f(x)=4x, x>0
What is f(−3)?-12-1512 - 6. Multiple ChoiceThe graph of f(x) is shown. What is the range for the domain x<−2?{y|y<−2}{y|y>−2}{y|y≤2}{y|y≥2}
- 7. Multiple ChoiceThe graph of f(x) is shown. What is the slope of the segment of f(x) with the greatest rate of change?1 ∕ 63 ∕ 516
- 8. Multiple ChoiceUsing the pictured graph, what is f(-3)?-3-113
- 9. Multiple ChoiceWhat is g when x equals -4?-16-3/25/216
