What is the minimum point on a graph of f(x) = (x - 1)² - 3?

mariarad [96]

Answer:

(1, -3)

First option

Step-by-step explanation:

The minimum point on the graph is also the <u>vertex</u>.

The quadratic function equation is given in <u>vertex form</u>, which is $f(x) = a(x - h)^{2} + k$

Using this equation, the vertex is (-h, k).

Whatever number you see for "h", find its opposite negative/positive. That will be the x-coordinate of the vertex. The y-coordinate for the vertex is the same as "k", keeping the negative and positive.

In f(x) = (x - 1)² - 3 using (-h, k) is:

h = -1 => -h = 1

k = -3

Therefore the vertex is (1, -3).

At the store deli, Rita spent $13.45 on 5 pounds of cheese.

defon

Answer:

$5.38

Step-by-step explanation:

$13.45 / 5 (To find the value of 1 pound of cheese, Total money spent divided by total pound of cheese bought)

$2.69 (1 pound of cheese will cost)

So, $2.69 x 2 (Multiply by 2 to find how much 2 pound of cheese will cost)

$5.38

After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

A pumpkin pie recipe says to bake the pie at 425°F for 15 minutes, and then to adjust the temperature down to 350°F for 45 additional minutes.

The function P(t) gives the oven temperature setting t, in degrees Fahrenheit, t minutes after the pie is placed in the oven.

Diego discovers that the temperature inside the oven is always 25 degrees warmer than the oven’s temperature setting.

The function B gives the actual temperature of Diego’s oven.

If P(30) = 350. Then the corresponding point on the function B will be

The temperature function can be written as

$P(t)=\begin{Bmatrix}425 & 0\leq t\leq 15 \\\\350 & 15 < t\leq 60 \\\end{Bmatrix}$
