Question

Find the value of
p(x)= x²
-3x-4 at x = -1, 1, 4​

Answer 1

Step-by-step explanation:

put x= -1

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

= 2-4

=2

Answer 2

Answer:

Given,

p(x)= x²-3x-4

if x = -1,1,4

p(-1) = (-1)² - 3(-1) - 4

= 1 + 3 - 4

= 4-4

= 0

p(1) = (1)²- 3(1) - 4

= 1 - 3 - 4

= 1 - 7

= -6

p(4) = (4)² - 3(4) - 4

= 16 - 12 - 4

= 4 - 4

= 0
