Da a funçao f(×)=3×+2calcule
A) F(-2) B) F(0) C) F(2) D) F(7)

Answer 1

Da a funçao f(×)=3×+2
calcule
A) F(-2)
f(x) = 3x + 2
f(-2) = 3(-2) + 2
f(-2) = - 6 + 2
f(-2) = - 4

 B) F(0)
f(x) = 3x + 2
f(0) = 3(0) + 2
f(0) = 0 + 2
f(0) = 2


 C) F(2)
f(x) = 3x + 2
f(2) = 3(2) + 2
f(2) = 6 + 2
f(2) = 8

 D) F(7)
f(x) = 3x + 2
f(7) = 3(7) + 2
f(7) = 21 + 2
f(7) = 23
