What is the value of f(4) + f(7)

1 answer:

7 0

Is there more to this problem? By saying f(4), you'd be inputting a 4 for every variable x. There is not enough info here to answer the question.

How to determine if a function is even or odd calculus?

aalyn [17]

A function $f(x)$ is even if $f(-x)=f(x)$ , and is odd if $f(-x)=-f(x)$ .

Example:

$f(x)=x^2$ is even, since $f(-x)=(-x)^2=x^2=f(x)$ .

$g(x)=x^3-x$ is odd, since $g(-x)=(-x)^3-(-x)=-x^3+x=-(x^3-x)=-g(x)$ .

what are the advantages and disadvantages to representing a function as an equation instead of a graph?

Oduvanchick [21]

Answer: See below:

Advantages as an equation: When you have an equation instead of a graph, you can use the equation to find exact values for a function. With a graph, don't always have the exact values. However, with an equation, you can find the exact input or output values.

Disadvantages as an equation: You don't get to see the overall picture or patterns in the function. With a graph, you can easily see the increasing and decreasing intervals of the function.

2. A square-based tent has the cross-sectional

ollegr [7]

(a) Length of the height is 2.732 m

(b) Length of the base is 5.466 m

<u>Explanation:</u>

An image is attached for reference.

(a)

In ΔAOB,

$sin 30^o = \frac{AO}{AB} \\\\0.5 = \frac{AO}{2} \\\\AO = 1 m$

In ΔBGD,

$sin 60^o = \frac{BG}{BD} \\\\0.866 = \frac{BG}{2} \\\\BG = 1.732 m$

According to the figure, BG = OE = 1.732 m

Height of the tent, AE = AO + OE

= 1 m + 1.732 m

= 2.732 m

(b)

DF = ?

In ΔAOB,

$tan 30^o = \frac{AO}{OB} \\\\0.577 = \frac{1}{OB} \\\\OB = 1.733 m\\\\\\$

According to the figure, OB = GE = 1.733 m

In ΔBGD,

$tan 60^o = \frac{BG}{DG} \\\\1.732 = \frac{1.732}{DG}\\ \\DG = 1m$

According to the figure, DE = DG + GE

DE = 1 m + 1.733 m

DE = 2.733 m

Length of the base, DF = 2 X DE

DF = 2 X 2.733 m

DF = 5.466 m
