Question

dada a funçao afim f(x)= -2x+3 determine:
a) f(0)
b) f(-1)
c) f(2)
d) f(0,5)

Answer 1

a) f(0) = -2(0) + 3 = 3
b) f(-1) = -2(-1) + 3 = 2 + 3 = 5
c) f(2) = -2(2) + 3 = -4 + 3 = -1
d) f(0,5) = -2(0.5) + 3 = -1 + 3 = 2

BONS ESTUDOS!

Answer 2

Dada a funçao afim f(x)= -2x+3 determine:
f(x) = - 2x + 3
a) f(0)
f(x) = - 2x +  3
f(0) = - 2(0) + 3
f(0) = - 0 + 3
f(0) = 3

b) f(-1)
f(x) = - 2x + 3
f(-1) = - 2(-1) + 3
f(-1) = + 2 + 3
f(-1) = 5

c) f(2)
f(x) = - 2x + 3
f(2) = - 2(2) + 3
f(2) = - 4 + 3
f(2) = - 1

d) f(0,5)
f(x) = - 2x + 3
f(0,5) = -2(0,5) + 3
f( 0,5) = - 1 + 3 
f(0,5) = + 2
