Question

find the value of P(x)=3x+1 at x=2,-½​

Answer 1

where x=2

1)p(2)=3×2+1

p(2)=6+1

p(2)=7

where x=-1/2

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

p(-1/2)=-1/2

hope helps you make me as brainlist

Answer 2

p(x) = 3x + 1

(a) at x = 2:

p(2) = 3(2) + 1

= 6 + 1

= 7

(b) at x = -1/2:

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

= -3/2 + 1

= (-3+2)/2

= -1/2
