Question

if P(x)=2xsquare-3x+4,find P(0),P(1) and P(-1)
find first degree polynomial with P(1)=1 and P(2)=3​

Answer 1

step by step Explanation :

$p(x) = 2x ^{2} - 3x + 4 \\ p(0) = 2 \times 0 ^{2} - 3 \times 0 + 4 \\ = 0 - 0 + 4 \\ = 4 \\ p(1) = 2 \times 1 ^{2} - 3 \times 1 + 4 \\ = 2 - 3 + 4 \\ = 5 \\ p( - 1) = 2 \times ( - 1) ^{2} - 3 \times ( - 1) + 4 \\ 2 - ( - 3) + 4 \\ 2 + 3 + 4 \\ = 9$
