This isn't a question, but if anyone is willing to with scatted plots and graphs etc. could you message me about it? i am really struggling in algebra.

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)

Abag contains 3 red marbles, 2 blue marbles, and 2 green marbles. one marble is picked, then another marble. assume that the selections are made with replacement. a) find the probability of picking two red marbles with replacement. b) find the probability of picking a red marble and a blue marble. assume the selections are made without replacement. c) find the probability of picking two red marbles without replacement. d) find the probability of picking a red marble and a blue marble without replacement.

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)
