What is the missing side length in this right triangle? 9 in & 12 in

Can someone me with the property questions for 12 13 and 14 plz

Which is f(5) for the function –2x2 + 2x - 3?

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.
