Q2. Linear Regression Model
Describe the Tranformations of the Sinsusoidal Function g(x)(black line) from the function f(x)(grey line).
g(x) = 2 f(1/2x) + 2
g(x) = 2 f(2x) + 2
g(x) = 2 f(1/2x) - 2
g(x) = 2 f(2x) - 2
Q3. Polar Functions
Which of the following equations makes a Cardiod on the positive x axis?
f(θ) = 2 + 3 cos(θ)
f(θ) = 3 - 3 cos(θ)
f(θ) = 3 + 3 sin(θ)
f(θ) = 3 + 3 cos(θ)
Q4. Exponential Functions
On the Interval (

The Function is negative and going furthur from the Polar Axis
The Function is negative and getting closer to the Polar Axis
The Function is positive and going furthur from the Polar Axis
The Function is positive and getting closer to the Polar Axis
