HELP!!!(LAST THREE QUESTIONS)

Which of the following is the function representing the graph below?

graph begins in the second quadrant near the x axis and increases slowly while crossing the ordered pair 0, 1. When the graph enters the first quadrant, it begins to increase quickly throughout the graph.

f(x) = 4x

f(x) = 4x − 3

f(x) = 4x + 3

f(x) = 4(x + 3)

The function f(x) = 396(3)x represents the growth of a dragonfly population every year in a remote swamp. Pierre wants to manipulate the formula to an equivalent form that calculates every month, not every year. Which function is correct for Pierre's purposes?

f(x) = 33(3)x

f(x) = 396(312)the x over 12 power

f(x) = 396(3 to the one twelfth power)12x

f(x) = 4752(3)x


For the graphed function f(x) = (4)x - 1 + 2, calculate the average rate of change from x = 2 to x = 4.

graph of f ox x equals 4 to the x minus 1 power, plus 2
