p(x) = 5x³ - 3x² - 7x - 1

p(-4) = 5(-4)³ - 3(-4)² - 7(-4) - 1

p(-4) = -5*64 - 3*16 + 28 - 1

p(-4) = -320 - 48 + 28 - 1 = -341

p(x) = 5x³ - 3x² - 7x - 1

p(-2/3) = -5*(8/27) - 3*4/9 + 14/3 - 1 = 23/27

p(x) = 5x³ - 3x² - 7x - 1

p(3/2) = 5*27/8 - 3*9/4 - 7*3/2 - 1 = -11/8

p(x) = 5x³ - 3x² - 7x - 1

p(i) = 5i³ - 3i² - 7i - 1 = -5i + 3 - 7i - 1 = 2 - 12i

p(x) = 5x³ - 3x² - 7x - 1

p(-i) = 5(-i)³ - 3(-i)² - 7(-i) - 1 = 5i + 3 + 7i - 1 = 2 + 12i

p(x) = 5x³ - 3x² - 7x - 1

p(3i) = 5(3i)³ - 3(3i)² - 7(3i) - 1 = 26 - 156i

p(x)= 5x³-3x²-7x-1

P(-4) = 5(-4)³-3(-4)²-7(-4)-1

=5*(-64)-3*16+28-1=-341

P(-2/3) = 5x³-3x²-7x-1

=5*(-8/3)-3*(4/9)+7*(2/3)-1=-11

P(3/2) = 5(3/2)³-3(3/2) ²-7(3/2) -1

=5*(27/8)-3*(9/4)-21/2-1=-1,375

P(i) = 5(i)³-3(i)²-7(i)-1

=-5i+3-7i-1=-12i+2

P(-i) = 5(-i) ³-3(-i) ²-7(-i) -1

=5i+3+7i-1=12i+2

P(3i)= 5(3i)³-3(3i)²-7(3i)-1

=-5*27i+27-21i-1

-156i+26
