Answer:
Graph or make a table of the function.
Step-by-step explanation:
When you graph the function just look on the graph to see that point is part of your function. Same would go for the table. Just look and see if your numbers match.
Do 580 divided by 20 then use the quotient ( answer) of that problem and divide that by 55
Those angles have to be equal
so 3x-25=6x-80
3x-6x=-80+25
-3x=-55
x=55/3
we are given

Firstly ,we can find equation in vertex form
so, we will complete x square



now, we can compare it with vertex form of equation

we can find h and k

so, vertex is
