Given the function f(x) = x2 – 7x+ 12, what is the
value of f(-5)?

If you meant X^2 then the answer is 22! :)

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
