Answer:
x = 5 ±
Step-by-step explanation:
Given
x² - 10x + 25 = 35 ( subtract 25 from both sides )
x² - 10x = 10
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 10 + 25
(x - 5)² = 35 ( take the square root of both sides )
x - 5 = ± ( add 5 to both sides )
x = 5 ±
That is the second option on list
Domain:
Range:
Explanation:
The function is
The domain of a function is the set of all input values for which the function is well defined. Generally, domain consists of all x-values of the function. Hence, the function is defined in the interval
.
The range of a function is the set of output values obtained by substituting the value of x in the function. Hence, the function is defined in the interval
.
