Question

4) Dada a função f(x): 3x - 7 determine: a) f(0) = b) f(1) = c) f(-2) =​

Answer 1

a) f(x) = 3x - 7

f(0) = 3.0 - 7

f(0) = 0 - 7

f(0) = -7

-----------------------------------------------------------

b) f(x) = 3x - 7

f(1) = 3.1 - 7

f(1) = 3 - 7

f(1) = -4

-----------------------------------------------------------

c) f(x) = 3x - 7

f(-2) = 3.(-2) - 7

f(-2) = -6 - 7

f(-2) = -13
