Question

A scientist sets up a pipette he will use to drip a chemical into a beaker full of water. The concentration of the chemical in the beaker over time is modeled by C(x), where x is time in minutes. Suppose the scientist adjusts the tube so that it drips into the beaker at triple its current rate.

How should C(x) be adjusted to model this?

C(x) should be vertically dilated by a factor of 3.

 

C(x) should be translated 3 units left.

 

C(x) should be translated 3 units right.

 

C(x) should be reflected across the x-axis.

Answer 1

C(x) should be vertically dilated by a factor of 3.

 

It doesn't what C(X) is, if linear or a quadratic, etc. Vertically it is just multiplied by 3 since it is zero at time = 0
