Which calculation works out a quarter of 12?
A 12 + 0.25 B 4 + 12 C 12 x 1
D 12 - 25 x 100

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

What is the point of inflection for the function f(x)=2cos4x on the interval (0, pi/2)

Someone answer this asap for the function f(x) and g(x) are both quadratic functions. f(x) = x² + 2x + 5 g(x) = x² + 2x - 1 which statement best describes the graph of g(x) compared to the graph of f(x)? a. the graph of g(x) is the graph of f(x) shifted down 1 units. b. the graph of g(x) is the graph of f(x) shifted down 6 units. c. the graph of g(x) is the graph of f(x) shifted to the right 1 unit. d. the graph of g(x) is the graph of f(x) shifted tothe right 6 units.
