Answer:

Step-by-step explanation:

What this means is when you start with P(x) you get 10^2 + 10x - 3 on the right

p(-4) has the meaning that when you see an x on the right hand side, you put in -4 for that x. Do this procedure for every x on the right.

p(-4) = 10(-4)^2 + 10(-4) - 3

p(-4) = 10*16 + (-40) - 3

p(-4) = 160 - 40 - 3

p(-4) = 120 - 3

p(-4) = 117
