This is not a trigonometry question. x^2 + 7x + (7/2)^2 = 11 + (7/2)^2 (x + 7/2)^2 = 23 1/4 x = -7/2 +/- sqrt(93)/2

Reiny, I interpret "inverse" being inverse trigonometric function, since he is doing a trigonometry course. However, I stand to be corrected!

I am surprised that you are studying trigonometry and don't know the basic shape of y = sinx Surely your instructor has taught you how to sketch the basic graphs before jumping to technology methods.

Replace with or replace for? Sentence: I want to replace algebra (with/for) trigonometry. If I use the word with, then does that's an I want trigonometry and not algebra? If I use the word for, then does that mean I want algebra and not trigonometry? Any rules?

determine the trend of each linear function: 1. f(x)= 3x+5 I don't know what you call the "trend" or why you call this a trigonometry question. It is about algebra. The value of the function increases with x at a rate of three times the change in x.
