Question

How do you evaluate the function when x = -3, 0, and 2 for p(x) = -7x - 5?

Answer 1

`16,-5,-19`

Explanation:

`"by substituting each of the values in turn into p(x)"`

`rArrp(color(red)(-3))=(-7xxcolor(red)(-3))-5=21-5=16`

`rArrp(color(red)(0))=(-7xxcolor(red)(0))-5=0-5=-5`

`rArrp(color(red)(2))=(-7xxcolor(red)(2))-5=-14-5=-19`
