its easier and faster to take the derivative of f(x) then find the value at x=2.4
df/dx=(x^2+4x)/(x+2)^2
substitute 2.4 for x
this gives df/dx (graph of the values of the slope at all points)
df/dx at x=2.4 is .7933884298

The "slope" tangent to any point on your graph is also known as the derivative. For example, the derivative of formula "x^2" is "2x" at any point on the graph. Once you obtain this formula, insert the known value of x into the new derivative formula, as was described by the person above.

dy / dx = 2(5x^2 + 7) * 10x .... at x = 1, dy / dx = 2*12*10= 240
