how do i do this problem: given g(x)=-x+4, find g(2a).

Substitute 2a for x.

g = 2a + 4

y=-3*+2 and y=3*-4

y=-3*+2 and y=3*-4

To find g(2a), you need to substitute 2a into the function g(x)=-x+4 and simplify the expression.

Step 1: Start with the function g(x)=-x+4.

Step 2: Replace x with 2a.

g(2a) = -(2a) + 4

Step 3: Simplify the expression.

g(2a) = -2a + 4

So, the value of g(2a) is -2a + 4.
