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.
