Does anyone know math or at least have an AI to help me solve this? I've tried Google and it hasn't helped

Evaluate the function f at the indicated values:
F(x)=5x-4
A. F(-a)
B. -f(a)

I know how to plug in real numbers but what about a? I've tried rewriting the whole equation with a instead of x and it says that's wrong, so idk what to do

A. F(-a)


Substituting -a for x:


F (-a) = 5(-a) - 4


=-5a - 4


B. -F(a)


First, find F (a):


F (a) = 5а - 4


Now, negate it:


-F(a) = -(5a - 4) = -5a + 4


Final Answers:


А. -5а - 4


B. -5а + 4
