DROPDOWN QUESTION
1 min • 5 pts
Answer explanation
a. f(5) = 6 - 3(5) => 6 - 15 = 9 | f(-4) = 6 - 3(-4) => 6 + 12 = 18 | -9 + 18 = 9
b. f(4) = 3 - 5(4) = 3 - 20 = -17
c. f(1/2) = 3(1/2)2 - 2(1/2) - 5 => 3/4 - 1 - 5 = - 31/4
d. f(3a+1) = 6(3a+1) - 5 => 18a + 6 - 5 = 18a + 1
e. 3x + 2 = -5 => 3x = -7 | x = - 7/3
substitusi x = - 7/3 ke f(x), sehingga
f(3(- 7/3) + 2) = 6(- 7/3) + 10
f(-7 + 2) = 2(-7) + 10
f(-5) = -4
