Question

Dada a f(x)=-2x+3, determine.

A)f(3)

B)f (-1)

C)f(2/3)

D)f (-3/2)

Answer 1

Explicação passo-a-passo:

f(x)= - 2x +3

f(3)= -2.3+3

f(3)= -6+3

f(3)= -3

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

f(-1)= 2 +3

f(-1) = 5

f(2/3) = -2.(2/3) +3

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

f(2/3) = - 4 + 9

______

3

f(2/3)= 5/3

f(-3/2)= - 2.(-3/2) +3

f(-3/2)= +6/2+3

f(-3/2)= 3+3

f(-3/2)= 6
