find the degree of the polynomial with P(1) =-1 and P(-2) =3A-4/3x + 1/3 =0B4/3x + 1/3 =0C4/3x - 1/3 =0D-4/3x - 1/3 =0Answer: A. -4/3x + 1/3 =0 Read Explanation: We have P(x) = ax +b P(1) = -1 ⇒ a + b = -1 .....(1) P(-2) = 3 ⇒ -2a + b = 3 ....(2) from (1) and (2) 3a = -4 a = −43\frac{-4}{3}3−4 a + b =-1 −43+b=−1\frac{-4}{3}+b=-13−4+b=−1⇒ b =−1+43=13-1+\frac{4}{3} = \frac{1}{3}−1+34=31 So, P(x)=−43x+13=0P(x) =\frac{-4}{3}x+\frac{1}{3} =0P(x)=3−4x+31=0 Read more in App
