F(x)= (√2x-7)/(x-3) what is the smallest possible integer for x such that f(x) real values? please show steps. Thank you! just in case it's not clear, I am trying to write the square root of 2x-7 divided by x-3. ​

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
