Question

Dada a função f(x) =2x -3,determine:
A) f (1) =
B) f (-1)=
C)f (0) =
D) f ( 1/2) =

Answer 1

Resposta:

Explicação passo-a-passo:

f(x) =2x -3,determine:

A) f (1) = > f(1) =2(1) -3 => f(1) = 2 -3 => f(1) = -1

B) f (-1)= > f(-1) =2(-1) -3 => f(-1) = -2 -3 => f(-1) = -5

C)f (0) = > f(0) =2(0) -3 => f(0) = 0 -3 => f(0) = -3

D) f ( 1/2) => $f(\frac{1}{2} }) = 2.\frac{1}{2} - 3 => f(\frac{1}{2} }) = \frac{2}{2} - 3 => f(\frac{1}{2} }) = 1 - 3 => f(\frac{1}{2} }) = - 2$
