What is the domain of the function f(x)= √x+6-7

x≥1

Step-by-step explanation:

f(x) = √x+6-7

f(x) = √x-1

The value under a square root must be non-negative; therefore make the inequality x-1 ≥ 0 and solve it.

x ≥ 1

There's your domain! Hope this helps! :D

Range:

(−∞,0)∪(0,∞),{y|y≠0}

Step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
