Question

if x is equal to 2 x cube minus 13 x square + 17 X + 12 then find f bracket minus 3​

Answer 1

Answer

f (x) = 2x³-13x²+17x+12

f(-3) = 2 (-3)³- 13(-3)² +17(-3) + 12

       =2* (-27) -13*9 - 51 +12

      = -54 - 117 -51 +12

      =-171 -39

     = -210

Answer 2

Answer:

we put f(x) as f(-3)

2x³-13x²+17x+12

2(-3)³-13(-3)²+17(-3)+12

2(-27)-13(-9)²+17(-3)+12

-54 -13× 9-51+12

-54-117-51+12

-53-117-39

-171-39

= -210
