## anonymous 5 years ago if I have f(x)=x^2-2x+5 how would this go into the diff quo (x+h)-(x) over h

1. anonymous

the difference quotient is $\frac{f(x+h) - f(x)}{h}$ So plug in x+h for x in f(x) for the first term in the numerator, and just plug in f(x) for the second term, then simplify.

[(x+h)^2 - 2(x+h) + 5] - [x^2 - 2x + 5] / h

Thanks thats what how I thought it was
