The graph of the function f(x) = (x + 2)(x + 6) is shown in the picture

tester [92]

Answer: The function is negative for all real values of x.where

x < -2.

Step-by-step explanation:

Because the values -4 and -6 are less than -2 which is the basis of the statement highlighted as the right one.

Regular pyramid B= P= H= l= LA= SA= V=

devlian [24]

Answer:

B (Base surface area) = 16 $m^{2}$

P (Perimeter of the base) = 16 m

H (Height) = 6 m

L (Not sure what L means. I assume it's the slant height??) = 6.32 m

LA (I assume lateral surface area) = $50.59 m^{2}$

SA (I assume total surface area) = $66.59 m^{2}$

V (volume) = $32 m^{3}$

Step-by-step explanation:

Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.

Graph the inverse circular function by hand, given f(x) = 3sin(2x) ;-pi/4 ≤ ≤pi/4

nasty-shy [4]

Part a)

a) The given function is

$f(x) = 3 \sin(2x)$

We let

$y = 3 \sin(2x)$

Interchange x and y.

$x= 3 \sin(2y)$

Solve for y;

$\frac{x}{3} = \sin(2y)$

$y = \frac{1}{2} { \sin}^{ - 1}( \frac{x}{3} )$

${f}^{ - 1}(x) = \frac{1}{2} { \sin}^{ - 1}( \frac{x}{3} )$

Part b) The range of f(x) refers to y-values for which f(x) exists.

The range of f(x) is

$- 3 \leqslant y \leqslant 3$

This is because the function is within y=-3 and y=3.

c) The range of

${f}^{ - 1} (x)$

$- \frac{ \pi}{4} \leqslant y \leqslant \frac{\pi}{4}$

The domain is -3≤x≤3

This is because the domain and range of a function and its inverse swaps.

Part d) The graph is shown in the attachment.
