The range of which function is (2, infinity)? y = 2x y = 2(5x) y = 5x 2 y = 5x 2
vova2212 [387]

The function which has range (2, infinity) from the provided function is y = 5ˣ +2. Option 4 is correct.

<h3>What is range of function?</h3>

Range of a function is the set of all the possible output values which are valid for that function.

The function whose range is (2, ∞) has to be find out.

The first function given in the problem is,

y=2^x

This function has the periodic function with period of logarithmic function and the range of this function is all the real number. This is not the correct option.

The second function given in the problem is,

y=2(5)^x

This function has the periodic function with period of logarithmic function and the range of this function is all the real number. This is not the correct option.

The fourth function given in the problem is,

y=(5)^x+2

This function is translated 5 units up to the function 5ˣ which has the range (0,∞).

Thus, the range of this function is (2, ∞).

Hence, the function which has range (2, infinity) from the provided function is y = 5ˣ +2. Option 4 is correct.

Tyrell and Channing both work at the same fast food restaurant. Channing works 5 hours and earns $42.75. Tyrell's earnings are m
kari74 [83]

Answer:

A. Channing makes $8.55 an hour compared to Tyrell who only makes $8 an hour.

Step-by-step explanation:

To find how much Channing makes an hour, divide the amount earned ($42.75) by the hours he worked (5). So, 42.75/5=8.55 which is Channing's hourly wage. Tyrell's hourly wage was already given to us in the equation E=8h. 8 times his hours works= his earnings. 8.55>8.00
