The exponential function in the graph shows the value, in dollars, of an investment over time. what real-world information is given by each feature of the graph?

Principle is the y-intercept.

The steepness and direction of the curve describes the rate/percent.

The x-values give the time interval.

The y-values give the overall total of the investment.

Step-by-step explanation:

An exponential function has specific characteristics which gives information from the real world situation.  The point (0,b) or y-intercept is always the starting value. For money, this is the principle or initial investment. The rate at which is increases or decreases is the steepness and direction of the curve. Steeper the line, the higher the rate. A curve starting high and ending low means a loss in value of the investment or decreasing value. A curve starting low and ending high means growth in the investment and more overall value.Each x-value is the time the investment is held. The y-values are the earned interest with the initial principle or total value of the investment.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
