Answer:
Third option.
Step-by-step explanation:
Some transformations for a function f(x), are:
If
, the function is shifted down "k" units.
If
, the function is shifted up "k" units.
If
, and
, the functio is stretch vertically by a factor of "b".
If
, the function is reflected over the x-axis.
Therefore, knowing that the parent function
was transformated by reflecting it over the x-axis, stretching vertically by a factor of 2 and shifting it down 3 units, we can determine that the following function represents the transformation:
Part A. Express the original claim in symbolic form.
Claim: <em>The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm.</em>

Answer:
<h2>
3y + 2 = 8</h2>
Step-by-step explanation:
solve A
2y - 3 = 19
2y = 22
y = 11
solve B
3y + 2 = 8
3y = 6
<h2>
y = 2</h2>
solve C
4y - 4 = -4
4y = 0
y = 0
solve D
5y + 1 = 10
5y = 9
y = 9/5
