Now that you have all the trained models in a list, use sapply() or map() to create a matrix of predictions for the test set. You should end up with a matrix with length(mnist_27$test$y) rows and length(models) columns. What are the dimensions of the matrix of predictions

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
