[AI-generated answer — Explain Bot]

To find the value of f(.5) for the function f(x) = 2x^2 - 5x, you need to substitute the value .5 in place of x in the function equation and evaluate the expression.

So, let's do that:

f(.5) = 2(.5)^2 - 5(.5)

First, square the .5:
(.5)^2 = 0.25

Now substitute the value and evaluate:
f(.5) = 2(0.25) - 5(.5)

Multiply:
f(.5) = 0.5 - 2.5

Combine like terms:
f(.5) = -2

Therefore, f(.5) is equal to -2.
