F(x)= -5x+2
its 4
The given expression is a linear function in the form f(x) = -5x + 2.
To evaluate this function for a specific value of x, you need to substitute that value into the function and then simplify.
For example, let's say we want to find the value of f(x) when x = 3. We can substitute x = 3 into the function:
f(3) = -5(3) + 2
Now, we simplify:
f(3) = -15 + 2
Finally, we get:
f(3) = -13
So, when x = 3, f(x) = -13.
