The vertex form of all expressions is given below.
We have given that the expressions
We have to write the function in vertex form.
<h3>What is the vertex form of the equation?</h3>
The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Therefore the first equation
it can be written as
The second equation can be written as
vertex for is,
The third equation is,
Vertex form is,
Forth equation is,
Vertex form is,

Answer: 12.1 years
Step-by-step explanation:
youd find 2.2% of 3000 which is 66 and then divide 800 by 66 to see how many years it would take to make 800 interest and you get 12.1 years. 90% sure on that answer btw
Answer: 2.5 miles per hour
Step-by-step explanation: ok, so we already know how long she walked in 1/2 hour and we need to find out how many miles in one full hour. So, i multiplied 1 1/4 times two to make up the one full hour and I got 2.5 miles. So the rate is 2.5 mph.xplanation:
Take one of the points in the table,
like x=1 y=5
or x=2 y=7
Write them into one of the choices on the list,
and see if the result is true.
For example,
-- Take the line in table that says x=1 y=5.
-- And take the first choice on the list y = x + 3 .
-- Write '1' in place of 'x', and write '5' in place of 'y'.
-- Then you have <u>5 = 1 + 3</u> .
Is this true ? I don't think so.
So the first choice on the list can't be correct.
Try thesame point x=1 y=5 with the other choices.
You'll find one that IS correct, and that's the answer.
