f(x) = 4x + 1
a)
f(4) = 4 * 4 + 1
f(4) = 16 +1
f(4) = 17
b)
f(-2) = 4 * -2 + 1
f(-2) = -8 + 1
f(-2) = -7
c)
f(-1) = 4 * -1 + 1
f(-1) = -4 + 1
f(-1) = -3
f(0) = 4 * 0 + 1
f(0) = 0 + 1
f(0) = 1
f(11) = 4 * 11 + 1
f(11) = 44 + 1
f(11) = 45
f(-1) + f(0) - f(11)
-3 + 1 - 45
-47
d)
f(3) = 4 * 3 + 1
f(3) = 12 + 1
f(3) = 13
2 * f(3) - f(3)
2 * 13 - 13
