Answer:

3/4

Step-by-step explanation:

It can be helpful to use a common denominator for comparison. That denominator can be 100, meaning we can make them all decimal fractions. Approximate (2 digit) values are good enough for the purpose.

2/3 ≈ 0.67 . . . . left end of the range

7/9 ≈ 0.78 . . . . right end of the range

3/5 = 0.60

6/9 ≈ 0.67 . . . . = 2/3, so is not greater than 2/3

3/4 = 0.75

6/7 ≈ 0.86

The only decimal value between 0.67 and 0.78 is 0.75, corresponding to the fraction 3/4.

2/3 < 3/4 < 7/9

Explain, in writing, what each parameter in the given function has on the graph of its parent function. (4 Points) () = −cos(1/2

Andrew [12]

Answer:

The parameters in the parent function are:

the parameter correspondig to - 3 in the given function is 0 in the parent function.
the parameter corresponding to 1/2 in the given function is 1 in the parent function, and
the parameter corresponding to - 1 in the given function is 1 in the parent function.

Explanation:

The given function is $f(x)=-cos(x/2)-3$ .

The parent function of $f(x)=-cos(x/2-3)\text{ }is\text{ }h(x)=cosx$ . The parameters of the given function are -1 (which is mutlyplying the value of cosine, 1/2 which is multiplying the argument (x), and - 3 which is subtracted.
