Physics
A 170 -pF capacitor is connected in series with an unknown capacitance, and as a series combination they are connected to a battery with an emf of 25.0 V. If the 170 -pF capacitor stores 135 pC of charge on its plates, what is the unknown capacitance?

calculus
We need the given interval

Algebra II
f(-1)=(-1)^2 -(-1)+1=3 g(3) =-3(3)+6=-3 3 times -3 = 9

math
f(x) = y y = 2log(base2)x =log(base2)x^2 therefore 2^y=x^2 so x = sqrt(2^y)

algebra
g(-5)=-4(-5)+3=23 f(23) = -2(23)-7 = -53 (f o g)(-5) = -53
