Question

# If f(x) = (25 – x2)1/2 then f( ) =…..

Hint:

### Put the given value of x in the given equation.

## The correct answer is: 2√5

### We have given the function of x as

f(x) = (25 – x^{2})^{1/2}

We have to find out the value of f()

f() = (25 – ()^{2})^{1/2}

= (25 – 5)^{ ½}

= 20 ^{1/2}

=2
