What is the range of f(x)=4•0.5^x?

Mathematics
1 answer:
VikaD [51]3 years ago
6 0

The range is the output, which would be the Y value.

The Y value would be calculated based on the input value for x.


any positive number raised to any value of x would be a positive number so 0.5^x would always be positive.

That would be multiplied by 4, which is a positive value, so the output ( Y value) would always be positive.


The range for this would be (0,∞)

Change the following algebraic expressions to the statement in words: i. 3mn +7 ii. xy + (x+y)
kicyunya [14]

Answer:

i) 3*m*n + 7

Then we can write the first term as:

"3 times the product between two numbers"

Where the product of two numbers is m*n

And after that we need to add 7, then the complete sentence is:

"3 times the product between two numbers, increased by 7"

ii) x*y + (x + y)

The first part, x*y, can be written as:

"the product of two numbers"

where the two numbers are the number x and the number y.

After that, we add the sum of these two numbers, then the complete sentence can be:

"the product of two numbers, plus the sum of these two numbers"

Verizon [17]

Answer:

(-1,-4)

Step-by-step explanation:

Because it is a rotation that turns both the x and y values the two swap places. The x value become negative because before it was in quadrant 4 where there was still a positive chance but rotating the point clockwise puts it into the third quadrant where there are only negatives.
