Exponential equation are functions defined by y =ab^x

The equation that could represent Rainey graph must take the form y =15b^x

<h3>How to determine the equation</h3>

An exponential equation is represented as:

y =ab^x

Where:

  • a represents the initial value
  • b represents the rate

The initial value (a) is 15.

So, the equation becomes

y =15b^x

The graph is not given;

So, the equation cannot be determined.

Assume that the rate is 2.

Then the function would be: y =15(2)^x

Let f and g be the functions defined by f(x) = 10^ (x+2 / 3) and g(x) = log (x3 / 100) for all positive real numbers,
Vaselesa [24]

Answer:

F(x) and g(x) are not inverse functions.

Step-by-step explanation:

In order to calculate the inverse function of a function, we have to isolate X and after that, we change the variables.

As our function f(x) is a exponentian function, we can apply logarithm with base 10 (log) in both sides in order to isolate X. Remember that log10=1.

[tex]y=10^{(x+\frac{2}{3}) }\\\\log y=log 10^{(x+\frac{2}{3}) }\\log y = (x+\frac{2}{3}) . log10\\\frac{log Y}{log10} = (x+\frac{2}{3})\\\frac{log Y}{1} = (x+\frac{2}{3})\\log Y-\frac{2}{3}=x[/tex]

Now we change the variables.

F(x)=log x-\frac{2}{3}

F(x) and g(x) are not inverse functions.

lbvjy [14]

Answer:

  On a coordinate plane, a curve starts in quadrant 3 and then increases into quadrant 1. It crosses the y-axis at (0, negative 2) and crosses the x-axis at (1.5, 0)

Step-by-step explanation:

The attached graph is an example of the square root function scaled and translated.

_____

No transformation of the square root curve will turn it into a parabola or into two curves.
