Dada a função f(x) -2x + 3, determine:

a) f(1)

b)f(0)

$c) \\ \frac{1}{3}$
$d) \ - \frac{1}{2}$

Answer 1

f(x) -2x + 3

(A)

f(1) = -2(1) + 3 = -2 + 3 = 1

(B)

f(0) = -2(0) + 3 = 0 + 3 = 3

(C)

f(1/3) = -2(1/3) + 3 = -2/3 + 3 = -2/3 + 9/3 = 7/3

(D)

f(-1/2) = -2(-1/2) + 3 = 2/2 + 3 = 1 + 3 = 4
