EOC.5 Algebra 1 Full Unit 5 Milestone Review

Front

Where is the function decreasing?

Back

The function is decreasing in the interval (-1, ∞).

Front

What is the rate of change between [2,4] for the function y=5(4)^x?

Back

The rate of change is 600.

Front

Write the explicit formula for the geometric sequence.

Back

The explicit formula is a_n = 100(1/2)^(n-1).

Front

Is the sequence -432, 72, -12, 2,... geometric?

Back

Yes, the sequence is geometric.

Front

Suppose a culture of bacteria begins with 5000 cells and dies by 30% each year. Write an equation that represents this situation.

Back

The equation is y=5000(0.7)^x.

Front

What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

Define the term 'rate of change'.

Back

Rate of change is a measure of how much a quantity changes in relation to another quantity, often expressed as a ratio.

Front

What is an explicit formula?

Back

An explicit formula defines the nth term of a sequence as a function of n.

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points in that interval, the function value at the second point is greater than the function value at the first point.

Front

What is the common ratio in a geometric sequence?

Back

The common ratio is the factor by which each term in a geometric sequence is multiplied to get the next term.
