Sagot :
f(3)= - 8
Step-by-step explanation:
f(x) = - 3x3 + 2x2 + 4x - 5
f(x) = - 9x + 4x + 4x - 5
f(3) = - 9(3) + 4(3) + 4(3) - 5
f(3) = - 27 + 12 + 12 - 5
f(3) = - 8
f(3)= - 8
Step-by-step explanation:
f(x) = - 3x3 + 2x2 + 4x - 5
f(x) = - 9x + 4x + 4x - 5
f(3) = - 9(3) + 4(3) + 4(3) - 5
f(3) = - 27 + 12 + 12 - 5
f(3) = - 8
