G(x) = 2[f(x)]^2 - 1 g(x) = 2[2x + 1]^2 - 1 g(x) = 2[4 x^{2}4x+1] - 1 g(x) = 4 x^{2} +4x+1 - 1 g(x) = 4 x^{2} +4x

If f(x)=sinx−1/cos2x, then limx→π2f(x) is equivalent to which of the following?
Harrizon [31]

Answer:

2

Step-by-step explanation:

Given g(x) = sin(x)-1/cos2(x), we are to find the limit if the function g(x) as g(x) tends to π/2

Substituting π/2 into the function

lim x-->π/2 sin(x)-1/cos 2(x)

= sin(π/2) - 1/cos(2)(π/2)

= 1 - 1/cosπ

= 1- 1/-1

= 1 -(-1)

= 1+1

= 2

Hence the limit of the function h(x) = sin(x)-1/cos2(x) as x--> π/2 is 2

The path a character takes to navigate a level of a video game is given in the following graph.
KonstantinChe [14]

We want to find the domain for the graphed function. We will see that the correct option is A: -12 ≤ x ≤ 14

<h3>What is the domain of a function?</h3>

For a function f(x) we define the domain as the set of possible inputs that we can use in the function.

In this case, we need to see the values in the horizontal axis that the graph covers.

We can see that it goes from -12 to 14. We also can see that there are two jumps, at x = -6 and at x = 8, but these values belong to the graph (denoted by the black dot) meaning that these are in the domain.

Then the domain is:

-12 ≤ x ≤ 14

Find the third side in simplest radical form
klasskru [66]

Answer:

2 \sqrt{71}  \: units

Step-by-step explanation:

Given is a right angled triangle in which third side is the hypotenuse.

Therefore, by Pythagoras theorem:

thid \: side =  \sqrt{ {15}^{2}  + ( \sqrt{59} )^{2} }  \\  \\  =  \sqrt{225 + 59}  \\  \\  =  \sqrt{284}  \\  \\  =  \sqrt{ {2}^{2} \times 71 }  \\  \\  = 2 \sqrt{71}  \: units
