Question 1070431: Consider the parent quadratic function f(x) = x2. Give the equation of a function that represents a horizontal translation of the parent, that is, it has moved right or left. (Many correct examples are possible.) Then give the equation of a function that represents a vertical translation of the parent, that is, it has moved up or down. (Many correct examples are possible.) Finally, give the equation of a reflection of the parent across the x-axis. (Only one correct answer exists.)

Question 1071159: Hello, I'm completely stuck on this question and have tried to find help in my textbook and notes but are unsuccessful. The question is
6. A bathtub which already had 25L in it is filling with warm water at the rate of 5L/minutes.
A- construct a rule for the bathtubs volume, V (L), in terms of time, t (mins).
My answer is V=25+5t
B- how much water will be in the bathtub after 7 minutes?
My answer is V=25+5(7), V=25+35, V=60
C- if the bathtub can only hold 250L, how long will it take before it is dull?
So I'm stuck on part C, I think I'd have to put the 250l= as the start of the equation but after this I'm lost, would you be able to help me please, thank you 🙂
