Evaluate the function rule for the given value. y=15*3^x for x = -3

Step-by-step explanation:

It is important to remember that an Exponential function has the following form:

Where  “b”  is and , "a" is a coefficient, "x" is the Independent variable and f(x) is the Dependent variable.

In this case, you have the following Exponential Function given in the exercise:

If the value of Dependent variable is -3, then:

So, you must substitute that value of "x" into the function:

And now you must evaluate:

1. According the Negative exponent rule:

Then:

2. Simplifying, you get:

answer: what equations are there

step-by-step explanation:

2x^2+5x+17
