Question

1) dada a função *F (x)=2x + 3* calcule:

a) F (1)

b) F (3)

c) F (-1)

d) F (0)

Answer 1

*F (x)=2x + 3* calcule:

a)
F(x) = 2x + 3
F (1) = 2.1 + 3
F(1) = 2 + 3
F(1) = 5

b)
F(x) = 2x + 3
F (3) = 2.3 + 3
F(3) = 6 + 3
F(3) = 9

c)
F(x) = 2x + 3
F (-1) = 2.(-1) + 3
F(-1) = - 2 + 3
F(-1) = 1

d)
F(x) = 2x + 3
F (0) = 2.0 + 3
F(0) = 3
