Question

Given f(x)=3x2−5x−2.

What is the value of f(−2/3)?

Answer 1

Explanation:

The absolute value of negative two third is really 2/3 but if your trying to reduce it to the lowest term its 0.66 or 0.67 However I would just put only 2/3 in the box, confidently knowing it would be scored correct.

Answer 2

`2\frac23`

Explanation:

Hello!

Evaluate the function for -2/3, by plugging it in for x in the equation.

Evaluate

• 
  `f(x) = 3x^2 - 5x - 2`
• 
  `f(-\frac23) = 3(-\frac23)^2-5(-\frac23)-2`
• 
  `f(-\frac23) = 3(\frac49) + (10)/(3) - 2`
• 
  `f(-\frac23) = \frac{4}3 + \frac{10}3 - 2`
• 
  `f(-\frac23) = 4 \frac23 - 2`
• 
  `f(-\frac23) = 2\frac23`

The evaluated value is
`2\frac23`.
