Mathematics
1 answer:
Rom4ik [11]3 years ago
6 0

Answer:

1. Yes

2. Yes

3. No

6. Yes

7. No

See descriptions and reasons why below.

Step-by-step explanation:

A function is a rule that assigns exactly one output to every input. This means that no input value (x value) can repeat and have different output values *y values).

1. Output values repeat for different input values. This is a function still.

2. Quadratic equations for a U shape graph and do not have repeating inputs so it is still a function.

3. A circle is not a function. It has repeating inputs. Draw a vertical line down through the circle. It intersects at more than one point. Not a function.

4. Not readable in the picture.

5. Not readable in the picture.

6. Yes it is a function. Draw a vertical line and it intersects only once. Therefore, it has no repeating inputs.

7. Not a function. The x values or inputs repeat 25 and 36 with different output values each time.

Apples went up 0.75 a lb

p is the start price so new price is p + 0.75

we buy 3 lbs

3 ( p+ 0.75) = 5.88

now solve

3p  + 2.25 = 5.88

     -2.25      -2.25

3p =  3.63

/3         /3  

p = 1.21 a lb
