Aculture of 1.75×1018 bacteria is in petri dish a. a culture of 6.25×1015 bacteria is in petri dish b. how many times greater is the number of bacteria in petri dish a than petri dish b? enter your answer, in standard notation, in the box.

Identify which functions are linear or non-linear. a. f(x) = x2 + 1 b. f(x) = 2x + 5 c. f(x) = x 2 + 3 d. f(x) = 3 x + 7 e. f(x) = 4x + 10 2 - 5

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.
