F(x) = 3x2 + 2x – 1 f(-1) =

f(-1) = 0

Step-by-step explanation:

Given information

f (-1) or x = -1

Given function

f(x) = 3x² + 2x - 1

Substitute values into the expression

f(-1) = 3 (-1)² + 2 (-1) - 1

Simplify the exponents

f(-1) = 3 (1) + 2 (-1) - 1

Simplify by multiplication

f(-1) = 3 - 2 - 1

Simplify by subtraction

f(-1) = 1 - 1

f(-1) =

Hope this helps!! :)

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
