Core Math Investigation 1) When x is more than 0 and increases (e.g. from 5 to 6), y increases at a much faster rate and becomes very big. When x increases when it is less then 0 (e.g. from -10 to -9), y increases very slowly. 2) (i) The value of a affects the value of x proportionally. For example we can compare the equations y = 1 + 2x and y = 5 + 2x. In the second equation, the value of a has been change to 5. As we can see from the results in Tables 1 and 2, all the values of y for y = 5 + 2x are greater by 4, when x is the same. (ii) As we have seen in (i), the effect of a does not affect the value of y, as it is a constant added to the solution of 2x . Hence, the...
