The given function is f(x) = 2x - 1 +10

Now we need to find the value of f(-5) which means we need to substitute x with -5 in the given equation.

Then,

f(x) = 2x - 1 + 10

f(-5) = 2(-5) - 1 + 10

f(-5) = -10 - 1 + 10 = -1

f(-5) = -1

Hence the value of the required function f(-5) is -1.

So option 3rd is correct.
