If ƒ(x) = 2x2 + 3, then which of the following represent ƒ(-1)? - 1 1 4 5

5

Step-by-step explanation:

Just change x to - 1:

f(- 1) = 2.(- 1)² + 3

f(- 1) = 2 + 3

f (- 1) = 5

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

answer: your correct answer is b. d.
