A student is in a 20 week calc class. The function f(t)=50-50e^0.2t f(t) measures the students problem speed in t weeks

-how many problems per hour can a student solve at the beginning of the course

- how many problems per hour can a student solve halfway through the course

-at what rate is the students problem speed increasing 6 weeks into the course

• Math -

at the beginning --- > t = 0
f(0) = 50 - 50e^0 = 0

half-way through course --- > t=10
f(10) = 50 - 50e^2 = -319

Your function is a decreasing function.
Why would the student's speed decrease as the course progresses ?

Check for typo.

• calc -

how to figure out rate
