If a and h are real numbers, find the following values for the given function.
f(x) = 7 − 3x
(a)Â
f(a) = 7-3a
(b)Â
f(−a) = 7-3(-a) = 7+3a
(c)Â
−f(a) = -(7-3a) = 3a-7
(d)Â
f(a + h) = 7 -3(a+h) = 7-3a-3h
(e)Â
f(a) + f(h) = (7-3a)+(7-3h) = 14-3a-3h
(f)
if h ≠0,
[f(a + h) − f(a)]/h = {[7-3a-3h]-[7-3a]}/h = [-3h]/h = -
