Question

Can someone please graph the following equation (not hand drawn) and tell me the maximum and x-intercepts:

y=(x tan 45°)-{[16(x^2)](1/100^2)[(sec 45°)^2]}

I got the answer but I want someone to verify it and I'm not very good at Excel. Thank you!

Answer 1

if you go to wolffram alpha you can type the equation in there and it will give you a graph and probably any other info you could possibly need
