Penjelasan dengan langkah-langkah:

f(x) = 7x + 5

a. f(6) – f(-2)

f(6) = 7(6) + 5

f(6) = 42 + 5

f(6) = 47

f(-2) = 7(-2) + 5

f(-2) = -14 + 5

f(-2) = -9

f(6) – f(-2)

47 – (-9)

47 + 9 = 56

b. f(4) + f(3)

f(4) = 7(4) + 5

f(4) = 28 + 5

f(4) = 33

f(3) = 7(3) + 5

f(3) = 21 + 5

f(3) = 26

f(4) + f(3)

33 + 26 = 59
