Answer:

s(x) is t(x) ...

horizontally compressed by a factor of 2,
reflected across the y-axis, and
translated downward 5 units.

Domain and Range

t(x) has a domain of x ≤ 0, and a range of y ≥ 0.
s(x) has a domain of x ≥ 0, and a range of y ≥ -5.

Step-by-step explanation:

t(x) is the square root function reflected across the y-axis and compressed horizontally by a factor of 2. That is, in f(x) = √x, the x has been replaced by -2x.

s(x) has the function t(x) reflected back across the y-axis and compressed horizontally by another factor of 2. It is also translated downward by 5 units, so that its origin (vertex) is at (0, -5).

_____

The graph shows you the domain and range of s(x). The domain is all numbers to the right of x=0, including x=0. That is ...

domain: x ≥ 0

The range is all numbers -5 or above:

range: y ≥ -5

___

For t(x), the argument of the square root function must not be negative, which means the value of x cannot be positive.

domain: x ≤ 0

For non-negative values of radicand, the t(x) function will have non-negative values. So, the range is ...

range: y ≥ 0

_____

The U.S Olympic Team has long distance runners who run a 10,000 meter race. If a runner was to run 50 races, how many centimeter

Ede4ka [16]

There are 100 centimeters in 1 meter. So to start with you must multiply 10000 by 100 to determine the number of centimeters in each race. This answer will be 1000000. Then to determine the number of centimeters in fifty races, you must multiply 1000000 by 50. This answer is 50000000. Then you must put it in scientific notation.

To do this you must move the decimal place over to the left until there is only one, nonzero number in front of it. Because you will move it to the left, your exponent will be positive. Therefore, your answer will be B.
