Question

if p(x)=x^2-4x-2 ,evaluate p(0)-p(-1)+p(-2)

Answer 1

Step-by-step explanation:

p(o) = 0-0-2=-2

p(-1) = 1+4-2=3

p(-2) = 4+8-2=10

so evalutating

-2-3-10=-15

hope it helps

Answer 2

Answer:

____________

• p(x) = x^2 - 4x - 2

_____________________

☞︎︎︎ i. p(0) = 0^2 - 4 × 0 - 2

= 0 - 0 - 2

= -2

☞︎︎︎ ii. p(-1) = -1^2 - 4 × -1 - 2

= 1 + 4 - 2

= 5 - 2

= 3

☞︎︎︎ iii. p(-2) = -2^2 - 4 × -2 - 2

= 4 + 8 - 2

= 4 + 6

= 10

➪ p(0) - p(-1) + p(-2)

➪ -2 - 3 + 10

➪ -5 + 10
