Pls answer this question

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

Find the zeros of each function. f(x) = x^2 + 5x - 6

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
