Answer:
Definitions
At the most basic level, an exponential function is a function in which the variable appears in the exponent. The most basic exponential function is a function of the form y=bx where b is a positive number.
When b>1 the function grows in a manner that is proportional to its original value. This is called exponential growth.
When 0>b>1 the function decays in a manner that is proportional to its original value. This is called exponential decay.
Graphing an Exponential Function
Example 1
Let us consider the function y=2x when b>1. One way to graph this function is to choose values for x and substitute these into the equation to generate values for y. Doing so we may obtain the following points:
(−2,14), (−1,12), (0,1), (1,2) and (2,4)
As you connect the points, you will notice a smooth curve that crosses the y-axis at the point (0,1) and is increasing as x takes on larger and larger values. That is, the curve approaches infinity as x approaches infinity. As x takes on smaller and smaller values the curve gets closer and closer to the x-axis. That is, the curve approaches zero as x approaches negative infinity making the x-axis is a horizontal asymptote of the function. The point (1,b) is on the graph. This is true of the graph of all exponential functions of the form y=bx for x>1.
hope it will help and if I am not wrong please give brain list
We know <em>a </em>is perpendicular <em>l</em> and that perpendicular means 90 degrees. Using corresponding angles, we know that <em>angle 3</em> also is 90 degrees. Using corresponding angles again, was know <em>angle b</em> is 90 degrees. Since 90 degrees is the same thing as perpendicular this would mean that <em>line b</em> is perpendicular to <em>line</em> <em>m</em>.<em />
The given states that line BC is congruent to line EC and line AC is congruent to line DC. By the vertical angles theorem, angle BCA is congruent to angle DCE. By SAS, triangle BCA is congruent to triangle DCE. Using CPCTC, it can be concluded that line BA is congruent to line ED.
