# If #f(x)=4x^2-24x+36#, how do you find the value f(x)=4?

To find the value of ( f(x) ) when ( f(x) = 4 ), set the given function equal to 4 and solve for ( x ):

[ 4x^2 - 24x + 36 = 4 ]

[ 4x^2 - 24x + 36 - 4 = 0 ]

[ 4x^2 - 24x + 32 = 0 ]

Now, solve the quadratic equation using methods like factoring, completing the square, or the quadratic formula.
