Hi, this is my first thing, and I was hoping we can talk here, im 12 and a girl, I hope we can talk

Describe the end behavior of the function below. f(x)=(2/3)^x-2 a. as x increases, f(x) approaches infinity. b. as x decreases, f(x) approaches 2. c. as x increases, f(x) approaches -2. d. as x decreases, f(x) approaches negative infinity.

Solve the following: 12(x^2–x–1)+13(x^2–x–1)=25(x^2–x–1) 364x–64x=300x

The equation of a parabola is given. y=18x2+4x+20 what are the coordinates of the focus of the parabola?
