Step-by-step explanation:
f(-5)=-5(-5)²+4
f(-5)=5(25)+4
f(-5)=125+4
f(-5)=129
The correct answer is B) the cost of removing 80% of pollutants is $196,000.
Using the equation, we have
240(80)/(100-80) = 240(80)/20 = 196
Since this is in thousands of dollars, we have 196,000.
Using the equation, A is not correct; it would be 160,000.
The vertical asymptote would be at 100%.
B must be the correct answer.
