MATEMÁTICA URGENTE!!!!!​

Answer 1

a) f(x) = x² - 6

f(-2) = 4 - 6

f(-2) = -2

b) f(x) = x² - 6

f(-1) = 1 - 6

f(-1) = -5

c) f(x) = 3x²+ x + 2

f(0) = 0 + 0 + 2

f(0) = 2

d) f(x) = 3x² + x + 2

f(2/3) = 3.(2/3)² + 2/3 + 2

f(2/3) = 12/9 + 2/3 + 2

f(2/3) = 4/3 + 2/3 + 2

f(2/3) = 6/3 + 2

f(2/3) = 4

e) f(x) = -x - 5

f(3) = -3 - 5

f(3) = -8

f) f(x) = -x - 5

f(4,5) = -4,5 - 5

f(4,5) = -9,5
