Find 𝑑𝑦/𝑑𝑥 and hence determine the rate of change of y with respect to x for the following algebraic functions:

Question

a. 𝑦 = 5E3𝑥−2𝑥E4
b. 𝑦 =2/𝑥E3 + 2𝑐𝑜𝑠4𝑥E2

Answer 1

If Ex means e^x, then use the chain rule
(a) y' = 5*3e^(3x) - 2e^4
(b) y' = -2/e^3 x^-2 - 2*4e^2 sin4x

I have never seen this confusing E notation
