3.(03.06) Using the completing-the-square method, rewrite f(x) = x2 + 4x – 1 in vertex form. (2 points)
O f(x) = (x + 2)2 + 1
O f(x) = (x + 2)2
O f(x) = (x + 2)2 + 4
O f(x) = (x + 2)2-5

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
