Step-by-step explanation:
------------->Then f(-2)
= f(x) : 3x2 + 2x - 8
= f(-2) : 3(-2)2 + 2(-2) - 8
= f(-2) : (-6)2 + (-4) - 8
= f(-2) : (-12) + (-4) - 8
= f(-2) : (-16) - 8
Step-by-step explanation:
f(x) = 3x2 + 2x – 8
———» Then f(-2)
f(-2) = 3(-2)^2 + 2(-2) - 8
f(-2) = 3((-2) × (-2)) + (2 × (-2)) - 8
f(-2) = 3(4) + (-4) - 8
f(-2) = (3 × 4) + (-4) - 8
f(-2) = 12 + (-4) - 8
f(-2) = 8 - 8
f(-2) = 0
