GMAS_Unit 4 & 5_Exponential Functions, Sequences and STAT

Which function represents this sequence?

(Hint: Decide the type of sequence then, use reference page )

If $$f\left(12\right)\ =\ 100\left(0.50\right)^{12}$$ , which expression gives $$f\left(x\right)$$ ?

(UNIT 2: Linear Functions Concept Question)

Which function is modeled in this table?

(Hint: Plug in ANY x value in each function to see if you the the same y value)

Which function represents the sequence?

(Hint: Determine the type of sequence, Use reference page for formula)

(Unit 3 Functions Concept Question

The set of ordered pairs shown represents a function $$f$$ .

$$\left\{\left(-5,\ 3\right),\ \left(4,\ 9\right),\ \left(3,-2\right),\ \left(0,\ 6\right),\ \left(1,\ 6\right)\right\}$$

Select TWO ordered pairs that could be added to the set so that $$f$$ remains a function.

(HINT: X- Values DO NOT in Tables and data sets)

(Unit 3 Function Concept Question)

The formula for the area of a circle is $$A\ =\ \pi r^2$$ . WHich equation shows the formula in terms of $$r$$ ?

The graph of am exponential function is hsown on the grid. Based on the graph, which statement about the function is true?

Which table represents an exponential function?

(Hint: outputs values (y) change by MULTIPLICATION)

A random group of high school students was surveyed. Each student was asked whether it should be mandatory for all high school students to participate in a sport. The results are partially summarized in the two way table.

In the freshman group, what percentage of students agree that it should be mandatory for all students to participate in a sport?

(Hint: Total the number of freshman surveyed first)

Which expression represents the number of dots for the $$nth$$ member of the pattern?

(Hint: Plug in the 1, 2 ,3 and 4 terms into each formula to see if you get the number of dots)
