Question

Dada a função afim f(x) = 8x + 16, determine os valores de x para que: a) f(1) b) f(5) c) f(0) d) f(1/2)

Answer 1

f (1)=8×1+16
8+16=24

f (5)=8×5+16
40+16=56

f (0)=8×0+16
0+16=16
f (1/2)=8×1/2+16
32+16=48

Answer 2

f(x) = 8x + 16

Determine os valores de x para que:

****************************
a)  x = 1

f(1)  = 8.1 + 16
f(1) = 8 + 16
f(1) = 24

************************
b)  x = 5

f(5) = 8.5 + 16
f(5) = 40 + 16
f(5) = 56

**************************
c) x = 0

f(0) = 8.0 + 16
f(0) = 0 + 16
f(0) = 16

***********************
d)  x = 1/2
f(1/2)

f(1/2) = 8x + 16
f(1/2) = 8. 1   + 16
                ---
                 2 

f(1/2) = 8/2 +16
f(1/2) = 4 + 16
f(1/2) = 20
