...Hi How do I approach the question below:
Let f(x)= 2x^2 - 5,g(x)= 3-4x, k(x) = 6x/(x^2-2)
Find the following and simplify:
e (f(x+h) - f(x))/h
I am extremely rusty.Can anyone help me solve these.Give me leads
For instance for a)g(-1)
Do I substitute 1 into the equation: g(x)= 3-4x
No, you have to substitute -1 in the equation g(x)=3-4x. so g(-1)=3-4*(-1)=7.
