right shows their data. homework
rebound
bounce
height
a. to what family does the function belong? explain how you know.
1/ 475 cm
2 /290 cm
3 / 175 cm
4/ 100 cm
5 / 160 cm
b. write the data as a sequence. is the sequence arithmetic,
geometric, or something else? justify your answer.

Answers

Just : c ) exponential.
It belongs to the square root family. Your answer is B. Why the square root family? Because y = (x+2)^{\frac{1}{2}} +3 can be written as y = \sqrt{(x+2)} + 3

When you raise to 1/2 or 1/3 it is like saying the square root or the cube root.
Exponential is the answer

I think it is Quadratic

Step-by-step explanation:

Exponential function

Step-by-step explanation:

The general form an exponential function is given by, y = a(b)^{x}.

Now, if we add another constant to the function as, y = a(b)^{x}  + c then the type of function does not alter.

Now, the function is given to be y = 2^{x} + 5 is a type of exponential function, where, a = 1, b = 2 and c = 5. (Answer)

c on edu

Step-by-step explanation:

i just took the quiz

B.square root

Step-by-step explanation:

Raising anything to the 1/2 power is the same as taking the square root of that term.

Since x would be under the square root sign (since it is part of the term being raised to the 1/2 power), this makes the function a square root function.

Option c is correct that is exponential function.

Step-by-step explanation:

We have been given a function:

y=2^x+5

Since, the function has something in power that is in its exponent.

Therefore, The given function is exponential

Therefore, option c is correct.

The function is not quadratic because quadratic function is of degree 2

The function is not square root because there is no square root symbol.

The function is not logarithmic because there is not written log anywhere.

Option c is correct that is exponential function.

Step-by-step explanation:

We have been given a function:

y=2^x+5

Since, the function has something in power that is in its exponent.

Therefore, The given function is exponential

Therefore, option c is correct.

The function is not quadratic because quadratic function is of degree 2

The function is not square root because there is no square root symbol.

The function is not logarithmic because there is not written log anywhere.

option a is correct.

Step-by-step explanation:

We have given the equation:

y=x+\frac{1}{2}^{\frac{1}{2}}+3

Squaring both sides of the above equation we get:

y^2=(x+\frac{1}{2})^2+9+2\cdot(x+\frac{1}{2})(3)

After simplifying the first  step

y^2=x^2+\frac{1}{4}+x+9+3(2x+1)

y^2=x^2+x+6x+3+9+\frac{1}{4}

y^2=x^2+7x+12+\frac{1}{4}

After final simplification we get:

4y^2=4x^2+28x+49

We are getting quadratic equation since, the degree in resultant is 2.

Therefore, option a is correct.
