Which statements accurately describes the function f(x)=3(718)? Select three options The domain is all real numbers. The range i

ollegr [7]

Answer:

A,C and E

Step-by-step explanation:

We are given that a function

$f(x)=3(\sqrt{18})^x$

We have to find three statements which describes function accurately.

Substitute x=0

$f(0)=3(\sqrt{18})^0=3$

We know that exponential is defined for all real numbers .

Given function is exponential function.

Therefore,

Domain=R

Range of f=y>0

Initial value means when x=0

Therefore, the initial value=3

$f(x)=3(\sqrt{18})^x=3(3\sqrt 2)^x$

The simplified base= $3\sqrt 2$

Point L (5, -4) is reflected across the line y = -x using the transformation rule (x, y) --> (-y, -x). What is the ordered pa

PilotLPTM [1.2K]

Answer:

L (4,-5)

Step-by-step explanation:

The transformation rule is (x,y) → (-y,-x) . This means that you are going to exchange your x and y and switch their signs.

1. Exchange - First you switch your points. (5,-4) → (-4,5)

2. Switch signs- -4 converts to 4 and 5 converts to -5

So your answer is L' (4,-5)
