I'm using Wolfram/Alpha for my son's Algebra 1 lesson on the Language of Functions. His book tells him to:
"1a. Use the DEFINE command to define f(x)=3x^2+2x+10 in your CAS. b. Find f(2). c. Find f(3) + f(-6)"
When I type it in like this: define f(x)=3x^2+2x+10 find f(2). It calculates properly.
How do I get it to "Find f(3) + f(-6)" in one step?
Thank you.
