Find the indicated value of the function fx squareroot x 4

Find the indicated value of the function f(x) = squareroot x + 4 - x + 2 Find the indicated value of the given function. (Simplify the answer as much as possible.) h(x) = x^2 + 3/x + 6

Solution

8) f(x) = (x + 4) - x + 2

f(2 - 2) = ((2 - 2) + 4) - (2 - 2) + 2

==> f(2 - 2) = (2 + 2) - 2 + 2 + 2

==> f(2 - 2) = (2 + 2) - 2 + 4

9) h(x) = x² + (3/x) + 6

h( + 5) = ( + 5)² + (3/( + 5)) + 6

==> h( + 5) = [ ( + 5)³ + 3 + 6( + 5) ] / ( + 5)

==> h( + 5) = [ ³ + 3²(5) + 3(5)² + 5³ + 3 + 6 + 30 ] / ( + 5) ; since (a + b)³ = a³ + 3a²b + 3ab² + c³

==> h( + 5) = [ ³ + 15² + 75 +125 + 33 + 6 ] / ( + 5)

==> h( + 5) = [ ³ + 15² + 81 +158 ] / ( + 5)
