The graph of an exponential function has a y-intercept of 9 and contains the point (2,144). Construct the function describes the graph.

Step-by-step explanation:

The exponential form observes the following form:

(Eq. 1)

Where:

, - Coefficients, dimensionless.

- Independent variable, dimensionless.

- Dependent variable, dimensionless.

According to the number of coeffcients, we need two different points such that all values are found. In this case, we know that:

,

And the resulting system of non-linear equations is described below:

(Eq. 1)

(Eq. 2)

From (Eq. 1), we find that:

And finally we solve (Eq. 2) for B:

The exponential function is , whose graph is presented below.

i don't even know man. edge inuity be messing with us. i had to ask a question too.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
