Question

dada a função de lei de f (x)=5×-2 calcule os valores de f (X) para:
A) f (x)=0

B) f (x)=2

C) f (x)= -1

D) f (x)= 1​

Answer 1

Explicação passo-a-passo:

f(x)= 5x -2

a) 0= 5x -2

2=5x

2/5=x

x=2/5

b)2=5x-2

2+2=5x

4=5x

4/5=x

x=4/5

c)-1=5x-2

-1+2=5x

+1=5x

1/5=x

x=1/5

d)1= 5x -2

1+2=5x

3=5x

3/5=x

x=3/5
