How do functions work? Could someone explain how to know which questions are functions or not

Mathematics
1 answer:
belka [17]3 years ago

Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a speceified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x  equals 2.

Step-by-step explanation:

here is a step by step equation:

f(x) = x + 7

if:

x=2

then:

f(2) = 2 + 7 = 9

A function is linear if it can be defined by

f(x) = mx + b

Makes sense? Hope I helped

plus I'm in middle school learning this also.

Determine the area of the circle, given each measurement. Use 3.14 for Pi and round to the nearest hundredth.
zimovet [89]

Answer:

314 in

Step-by-step explanation:

The area of a circle is pi* r^2

If the radius is 10, then it is

pi* 10^2= 100pi

100*3.14 is around 314.16, using 3.14 for Pi it will be 314

A helicopter floats 120m above a helipad, a dog is 85m from the helipad, if the dog could fly, how far would it have to fly to g
suter [353]

<em>If the dog could fly, it would need to fly 147 meters to catch the helicopter</em>

This is a rather easy and straightforward question. We are going to solve it using Pythagoras theorem. We can interpret the question to be in a triangle where the height of the helicopter above the helipad and away from the dog is the right angle. This also means that the distance needed, between the dog and the helicopter is the hypotenuse.

Using pythagoras theorem, we have

120² + 85² = c²

c² = 14400 + 7225

c² = 21625

c = \sqrt{21625}

c = ±147 meters.

Since distance cant be in the negative, our answer is 147 m
