What is the range of the function<br> f(x) = (x - 1)? when the domain is {-5, 0,5}?

Nimfa-mama [501]

Answer:

f(x) = (x - 1)2

f(x) = 2x - 2

let x = -5, f(x) = -12

let x = 0, f(x) = -2

let x = 5, f(x) = 8

range is {-12, -2, 8}

Which of the following comparisons is FALSE?

dybincka [34]

Answer:

Step-by-step explanation:

Let's check each one-by-one.

we know 3.79 liters is 1 gallon, so 4 liters IS NOT LESS THAN 1 gallon

THis is false.

We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.

This is true.

we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.

THis is true.

We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles

So definitely 9 miles IS GREATER than 10 km.

THis is true.

So answer choice A is false, only.
