Assume f(x) = -2x + 8 and g(x) = 3x. What is the value of (f + g)(-1)?
To find the value of (f + g)(-1), we need to substitute -1 into the expression for (f + g)(x).
Now let's calculate:
f(x) = -2x + 8
g(x) = 3x
(f + g)(x) = f(x) + g(x)
= (-2x + 8) + (3x)
= -2x + 8 + 3x
= x + 8
Now, substitute -1 into the expression (f + g)(x):
(f + g)(-1) = (-1) + 8
= 7
Therefore, the value of (f + g)(-1) is 7.
