t = (v - u) / a

f^-1(x)=(e^x-1)/3 g(x)=3/(3x+1)

The gradient is always the number in front of the x, in this case it will be 3. Whereas for the y-intercept, it will always be the value that y equates to when x=0, in this case the y-intercept is (0,4).<...

To do this question you would use the FOIL method. This is short for 'First, Outside, Inside, and Last'. First you multiply the first two values (the x's) from each bracket, then you multiply the outside ...
