The current student population of San Francisco is 2100. If the population increases at a rate of 17.4% each year. What will the student population be in 9 years? Write an exponential growth model for the future population P(x) where x is in years:
P(x)=

What will the population be in 9 years? (Round to nearest student)=

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
