Question

given p(t)=4t^4+3t^3-t^2+6 find p(-1)

Answer 1

Step-by-step explanation:

We substitute the variable t=p the given polynomial r(t)=4t

4

+3t

3

−t

2

+6 as follows:

r(p)=4p

4

+3p

3

−p

2

+6

Hence, the value of the given polynomial with t=p is r(p)=4p

4

+3p

3

−p

2

+6.

Answer 2

Answer:

p(-1)=4(-1)⁴+3(-1)³-(-1)²+6

= 4(1)+3(-1)-(1)+6

= 4-3-1+6

=4-4+6

=6
