What is the integral of e^x?

• e^x
• -e^x
• e^x +C
• -e^x + C

The rate of change of Y with respect to x is proportional to the difference of x and z

• dx/dy = x-z

• dy= k(z-x)

• dy/dx = k(x-z)

• dz/dx = z-x

2. Solve the differential equation

𝑑𝑦/𝑑𝑡 =3𝑡²/𝑦 with initial condition

𝑦(2) = 0.

• 𝑦 = ln(15t)

• 𝑦 = 16t³

• 𝑦 = (2𝑡³ − 16)^1/2

• 𝑦 = (2𝑡³ −16)
