how can this be done?
Given the function
(i) Find the equation of the tangent to the function at the point x = 1 in the form
where m and c are numbers. Express m and c as whole numbers and not decimals

The tangent is a straight line, so will have a gradient and a y intercept.
You know a point that lies on the tangent, it's at x = 1 (what's the corresponding y value?)
How are you going to evaluate the gradient of the tangent at that point? Hint: It's the same as the gradient of your curve at that point...
