<em>Look at the step-by-step explanation to get a better understanding</em>
Step-by-step explanation:
Domain = {x | x is a real number}
The function shown f(x)=5^x-7 is an exponential function with a vertical shift of -7 units (shift downwards). Nevertheless, it is an exponential function.
Domain is the set of x-values that we can put into the function. Exponential functions of this type have a domain of "all real numbers". If you see the function, you can figure out that we can put any real number and still there will be no "undefined" or "division by zero" cases.
Thus, this function's domain is the set of all real numbers.
Domain = {x | x is a real number}

Answer: $ 45,444.44
Step-by-step explanation:
Given: Jill budgets 18% of her yearly salary for clothing.
His total clothing bill for the year is $8,180.
Let x= her yearly salary
Then according to the question , we have
18% of x = 8180
Convert 18% into decimal by dividing it by 100 , we get
0.18 x= 8180
Multiply both sides by 100
⇒ 18x = 818000
Divide both sides by 18 , we get
x= 45444.44
Hence, her yearly salary = $ 45,444.44
