Respuesta de (-0.5)²
Vladimir79 [104]

Answer:

0.25

Step-by-step explanation:

we have

(-0.5)^2

we know that

-0.5=-\frac{1}{2}

substitute

(-\frac{1}{2})^2=(-\frac{1}{2})(-\frac{1}{2})

Remember that

(-1)(-1)=1\\(-1)(1)=(-1)

so

(-\frac{1}{2})(-\frac{1}{2})=\frac{1}{4}=0.25

What is the value of the function when x = 1?
creativ13 [48]

On the graph, we can see that when x=1, y=0.

But we don't even need to bother opening the attachment
and studying the graph !

In your question, you said that one point on the function is  (1, 0) .
That means that when 'x' is 1, 'y' is zero.  And there you are !
