Which of the following graphs represents a function?

Mathematics
1 answer:
Evgesh-ka [11]3 years ago
4 0

For something to be a function, each input (x value) can only have ONE output (y value)

If an input has multiple outputs, it is not a function.    

so the last graph represents a function (parabola going down)

A hiker is walking down a mountain. She walked​ 5,978 feet in 17 minutes. In that​ time, she descended​ 1,024 feet from the top
olya-2409 [2.1K]

Answer:

63.5 feet/minute

Step-by-step explanation:

She first descended 1,024 feet in 17 minutes

Then she descended 500 feet in 7 minutes

The total feet descended is 1,024 + 500 = 1,524 feet

The total time to descend is 17 + 7 = 24 minutes

The average rate of change in altitude is  

Altitude descended / time

1,524 feet / 24 minutes

63.5 feet /minute

Which equation describes how the parent function, y = x cubed, is vertically stretched by a factor of 4?
storchak [24]

The equation that describes how the parent function, y = x³, is vertically stretched by a factor of 4 is y = 4x³.

<h3>We can find how the equation is vertically stretched below:</h3>

When an equation is vertically stretched, it means that the parent equation has been multiplied by a number that is more than one.

This means that the equation is multiplied by some factor.

It is given that we should describe how the parent function is vertically stretched by a factor of 4.

The parent function is given as y = x³.

Since the equation is said to be vertically stretched by a factor of 4, we must multiply the parent equation by 4 to stretch it.

Therefore, we have found the equation that describes how the parent function, y = x³, is vertically stretched by a factor of 4 to be y = 4x³.
