Last year, there were 223 pies baked for the bake sale. This year, there were d pies baked. Using d , write an expression for the total number of pies baked in the two years.

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
