The students in an Algebra 2 class took a final exam at the end of the class. Then they were given equivalent forms of the exam at monthly intervals. The model a(t) = 90 – 15 log(t+1) was used to predict the average score a after t months. Describe how the model is transformation from f (t) = log(t)
The graph of f(t) = log(t) is reflected across the x-axis, vertically stretched by a factor of 15, and translated down 90 and left 1 unit
The graph of f (t) = log(t) is reflected across the x-axis, vertically compressed by a factor of 15, and translated up 90 and left 1 unit
The graph of f (t) = log(t) is reflected across the x-axis, vertically stretched by a factor of 15, and translated up 90 and right 1 unit
The graph of f(t) = log(t) is reflected across the x-axis, vertically stretched by a factor of 15, and translated up 90 and left 1 unit
