Paul works at a car wash company. • The function f(x) = 10.00x + 15.50 models his total daily pay when he washes x cars,
• He can wash up to 15 cars each day.
What is the range of the function?
А 0<_f(x) <_165.50

B. 0<_f(x) <_15, where x is an integer

C. {5.50, 10.50, 15.50, .
..., 145.50, 155.50, 165.50}

D. {15.50, 25.50, 35.50, ..., 145.50, 155.50, 165.50)

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
