The ordered pair (x,5) is a solution to the function f(x) = x^2 + 1

x = ± 2

Step-by-step explanation:

Given

f(x) = x² + 1 and (x, 5 ) is a solution then f(x) = 5

Equating the two gives

x² + 1 = 5 ( subtract 1 from both sides )

x² = 4 ( take the square root of both sides )

x = ± = ± 2

Thus (- 2, 5) and (2, 5) are solutions

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
