Are we to assume that v is a velocity function? If so then where x is the displacement function. To go from v to x, you need to "reverse" the derivative which means find the anti-derivative or integral. Integrating this directly will give x as a function of t. But it is not too hard to solve the given equation for t as a function of v and then just replace t.

Two other points: your formula is missing a right parenthesis ")" so it is a little ambiguous. "Displacement" means distance from a specific point. What specific point are you talking about? The position at t= 0? Since integrating will introduce a "constant of integration", you will need to know that to find a value for the constant.
