Answer:
its alot to explain but i will try to make it as simple as possible
Step-by-step explanation:
your first goal is to make each problem into the form ax^2+bx+c=0
number 1, 2, 7 and 8 is already done for you
now all you have to do is plug in each number in the standard form into the quadtratic formula.
basically at this point you can just use your calculator to do the rest of the work. dont forget parentheses so it doesnt get confused...
or you can perform the algebraic work.. its all just a matter of plugging in the right numbers into the quadratic formula...
cant really do the work for you since im on my phone. but yeah all you need to do step one is transform each problem into ax^2+bx+c=0 form
then step 2, plug in each number in to the quadtratic formula. from there calculate using basic algebraic rules
f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.
, written in vertex form is
, where (h, k) = (-1, -11)
Therefore, range ={y|y ≥ -11}
Time zones<span> and </span>time<span> offsets. A </span>time zone<span> is a geographical region in which residents observe the same standard </span>time<span>. A </span>time<span> offset is an amount of </span>time<span> subtracted from or added to Coordinated Universal </span>Time<span> (UTC) </span>time<span> to get the current civil </span>time<span>, whether it is standard </span>time<span> or daylight saving </span>time<span> (DST)
I hope my answer has come to your help. God bless you and have a nice day ahead!
