Find the gradient of the curve y = 5(x^2} - 2x + 3 when x = 4

First, you would need to differentiate the equation. To find the differential, multiply the power of x by the coefficient, then reduce the power by 1. You should see that any constants will not be seen in the differential. The differential of the equation is 10x - 2. You should then substitute x=4 into the equation. This should give an answer of 10(4) - 2 = 38.
