The parent function f(x) = x3 and its translation, g(x), are shown on the graph.
A
g(x) = (x – 5)3 + 3B
g(x) = (x + 3)3 – 5C
g(x) = (x – 3)3 + 5D
g(x) = (x + 5)3 – 323

A chemist has 500 mL of a 30% acid solution. She adds x milliliters of a 10% acid solution. Which statement is true about the graph of the function that represents the concentration of the final solution?
A
The horizontal asymptote y = 30 means that the final concentration will always be less than 30%.B
The horizontal asymptote y = 10 means that the final concentration will always be greater than 10%.C
The vertical asymptote x = 500 means that the volume of the solution will always be greater than 500 mL.D
The vertical asymptote x = 0 means that the volume of the solution will always be greater than 0 mL.Did you find these answers helpful?
