Question

considere a função f R→Rdefinida por f(x) = 5x + 2. Calcule f(0), f(2), f(-3), f(2/3)URGENTEEEEEEEEEEEEEEEEE

Answer 1

Resposta:

f(x) = 5x + 2

f(0)= 5.0 + 2 = 2

f(2)= 5.2 + 2= 12

f(-3)= 5.-3 + 2= -13

f(2/3)= 5.2/3 + 2 = 10/3+2 = 16/3

Answer 2

*F(0)

F(x) = 5x + 2

F(x) = 5. 0 + 2

F(x) = 5 + 2

F(x) = 7

*F(2)

F(x) = 5x + 2

F(x) = 5 . 2 + 2

F(x) = 10 + 2

F(x) = 12

*F(-3)

F(x) = 5x + 2

F(x) = 5 . (-3) + 2

F(x) = -15 + 2

F(x) = -13

*F(⅔)

F(x) = 5x + 2

F(x) = 5 . 3/2 + 2

F(x) = 5 . 0,6 + 2

F(x) = 3 + 2

F(x) = 5
