A. The domain is all real numbers less than or equal to 4,
and the range is all real numbers such that -3 5x31.
B. The domain is all real numbers such that -3 SX S1, and
the range is all real numbers less than or equal to 4.
C. The domain is all real numbers, and the range is all real
numbers less than or equal to 4.
D. The domain is all real numbers less than or equal to 4,
and the range is all real numbers.

idk

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
