Given ​ f(x)=x^2−2x−5​. <br><br> Enter the quadratic function in vertex form.
FrozenT [24]

Answer:

f(x) = (x-1)^2-6

Step-by-step explanation:

Rewrite the quadratic using the method of completing the square:

x^2-2x-5=(x^2-2x+1)-1-5=(x-1)^2-6\\f(x) = (x-1)^2-6

From this form it is immediately clear that the vertex of the parabola is at x=1 and its y-intercept at -6.

Some one explain this to me
lubasha [3.4K]
7.50
25% also equals 1/4 so divide 130.00 by 4 which equals 32.50
subtract 32.50 from 130.00 which equals the cost, 97.50
97.50 minus 90$ is 7.50, therefore that is the answer

All you have to do is find (3/10) of 60, and find the triangle with that number
for its label.

The exact same kind of problem was answered correctly by 2 people for the question you posted 9 minutes earlier, and one of them even explained how
he did it.  If you're getting anything more than answers from Brainly ... I mean
if you're actually getting HELP here ... then you ought to be able to answer
this one on your own.
