How to tell if its identifying functions is a function or not

1 answer:

Svetach [21]3 years ago

Answer:

Step-by-step explanation:

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

Calculate the following values:

adelina 88 [10]

F(a)=a^2-5a+7

F(a+h)=(a+h)^2-5(a+h)+7
=a^2+2ah+h^2-5a-5h+7

F(a+h)-F(a)=(2ah+h^2)/h

Factor out h, we will have h(2a+h)/h, the answer is 2a+h

Solve the following maximization problem graphically.

rjkz [21]

The maximized value of the function is (c) 119/2

<h3>Maximization problem</h3>

Maximization problems are used to determine the optimal solution of a linear programming model

<h3>Objective function</h3>

The objective function is given as:

$P(x,y) = 11x + 10y$

<h3>Constraints</h3>

The constraints are given as:

$22x + 2y \le 68$

$8x + 16y \le 68$

$x,y\ge 0$

<h3>Graph</h3>

See attachment for the graph of the constraints

From the graph, the optimal solution is: (2.83, 2.83)

So, the maximized value is:

$P(x,y) = 11x + 10y$

$P =11 \times 2.833 + 10 \times 2.833$

$P =59.493$

Approximate

$P =59.5$

Rewrite as a fraction

$P =\frac{119}{2}$

Hence, the maximized value of the function is (c) 119/2
