Using a calculator, we see that
-1/2 = -0.5
-1/3 = -0.333 approximately
So saying "some number between -1/2 and -1/3" is roughly the same as saying "some number between "-0.5 and -0.333". Choice A can be ruled out because -0.53 is not between -0.5 and -0.333. Choice B can be eliminated for similar reasons. The same story happens with choice D as well.
The only possible answer is choice C. The values -0.4 and -0.454545... are between -0.5 and -0.333... so that helps confirm the answer

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 8x² + 5x - 2
x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 8(-2)² + 5(-2) - 2
- Exponents: f(-2) = 8(4) + 5(-2) - 2
- Multiply: f(-2) = 32 - 10 - 2
- Subtract: f(-2) = 22 - 2
- Subtract: f(-2) = 20
