Step-by-step explanation:

F(-2) for f(x) =5•3^x

Then, replace x by - 2

F(-2)=5•3^-2 (RULE= 3^-2 = 1/3^2)

$= 5. \frac{1}{ {3}^{2} }$

$= 5 . \frac{1}{9}$

$= \frac{5}{9}$

Hope this helps..have a great day!

Answer:

5/9

Step-by-step explanation:

f(x) =5•3^x

Let f = -2

f(2) =5•3^-2

= 5 * 1/ 3^2

= 5 * 1/9

= 5/9

To start, we're given the range that x lies in: from -1 to 4. We know from the fact that $-1 \leq x$ that -1 will be <em /><em>included</em> in that range, so we mark -1 on the number line with a solid circle. We also know from $x\ \textless \ 4$ that, while x can be any value <em>up to</em> 4, it does not <em>include </em>4. We indicate this by drawing a hollow circle around 4 on the number line. Since x can be <em>any value within this range</em>, we make that fact clear by drawing a bold line between the points -1 and 4 on the number line. I've attached an image of what our final graph would look like.

Consider the function. What is the y-intercept of f–1(x)? –16 –12

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

$f(x)=x^2+2x-16$

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set $x=0$ . In other words, we define the y-intercept (let's call it $b$ as:
