Answer:
Domain = {x | x is a real number}
Look at the step-by-step explanation to get a better understanding
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}
