we have
Find the roots
Equate the function to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
therefore
<u>the answer is</u>
Answer:
<h2>Function 1 has the least minimum value and its coordinates are (2. - 7).</h2>Step-by-step explanation:
The first function is
The second function is
x g(x)
-2 2
-1 -3
0 2
1 17
The vertex has coordinates of , where
and
.
Let's find the vertex for the first function where and
.
Therefore, the vertex of the first function is at .
Now, the minimum value of the second function can be deducted from its table, which is .
Therefore, has -7 as minimum value and
has -3 as minimum vale.
So, the right answer is B, because -7 is less than -3.
