What transformation is made from f(x) → f(-x)?

sineoko [7]

Answer:

A) reflection across the y-axis

Step-by-step explanation:

If $f(x)=f(-x)$ , then this says that two $y$ -coordinates are equal for opposite values of $x$ .

Let $(a,b)$ a point on $f$ .

Then $f(a)=b$ .

We also know that $f(-a)=b$ and therefore $(-a,b)$ is also a point on the graph.

If you graph [/tex](-a,b)[/tex] and $(a,b)$ you will see they are symmetrical to each about the $y$ -axis.

Example if given both $f(x)=f(-x)$ and $f(2)=3$ , then $f(-2)=3$ . This means both (2,3) and (-2,3) are points on the graph.

Here is what those two points look like on a Cartesian Plane (please see graph in picture).

I need help with the photo below.

PSYCHO15rus [73]

Here, 30/360 * 2πr = 10
1/12 * 2 * 3.14 * r = 10
r = 10*12 / 6.28
r = 19.11

Now, Area = 1/12 * 3.14 * (19.11)²
= 3.14/12 * 365.16
= 95.5 Ft²

In short, Your Answer would be Option C

Hope this helps!

Pls help (kinda easy)

3241004551 [841]

Answer:

$f(x)=(2x+1)(2x-1)$ .

Step-by-step explanation:

We want to convert the function into the form that let's us easily find the x-intercept, and it would be for the form $(ax+b)(cx+d)$ because then we can find the x-intercept in the following manner:
