Connor is using a computer program to graph the function H (n) = - 13n - 421. He wants to see the intercepts. Which minimum values should he use to set up the viewing window?

I can't see any slick, easy way to tell without finding

the intercepts, so here goes:

The y-intercept is the value of H (n) when 'n' is zero.

H (0) = - 13 (0) - 421

= - 421.

The n-intercept is the value of 'n' when H (n) is zero.

0 = - 13n - 421

Add 13n to each side: 13n = - 421

Divide each side by 13 : n = - 421/13 = - 32.4 ...

Connor should set up the viewing window so that 'n' displays

at least down to - 33, and H (n) displays at least down to - 421.
