Answer:
Step-by-step explanation:
either b or c not sure
<span>For this case we have the following function:
</span>

<span> To find the axis of symmetry, the first thing to do is to derive the function.
We have then:
</span>

<span> Equaling zero we have:
</span>

<span> We clear the value of x.
We have then:
</span>

<span>
Answer:
The axis of symmetry is given by:
x = -2</span>
(-6,0) is a point of an x- intercept in this function
Answer:
10
Step-by-step explanation:
(U can do mental calculation and guess it will be 10 ..) or else ....
Constant(k) = xy
k= 5 x 20
k= 100
Constant(k) = xy
100 = xy
100 = 10y
y= 100/10 = 10
= 10
I hope im right!!
