So remember that \sqrt{x}  \sqrt{y} = \sqrt{xy} so \sqrt{-18} = \sqrt{9}  \sqrt{-1}  \sqrt{2} =3i\sqrt{2} \sqrt{-2} = \sqrt{-1} \sqrt{2} =i\sqrt{2} i\sqrt{2}+3i\sqrt{2}=\sqrt{2}(i+3i)=\sqrt{2}(4i)=4i\sqrt{2} answer is second one or 4\sqrt{2}i

V ( x ) =12-2x-5 when x= -2,0,5 solve step by step
BlackZzzverrR [31]

v(-2) = 11,  v(0) = 7,  v(5) = -3.

hope this helps! :)

v(x) = 12 - 2x - 5\\v(-2) = 12 - 2(-2) - 5\\v(-2) = 12 + 4 - 5\\v(-2) = 11\\-----------------------------\\v(0) = 12 - 2(0) - 5\\v(0) = 12 - 0 -5\\v(0) = 7\\-----------------------------\\v(5) = 12 - 2(5) - 5\\v(5) = 12 - 10 - 5\\v(5) = -3

How does replacing f(x) with f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative) affect
ivann1987 [24]
F(x) + k - Moves the graph k units up.

k f(x)   stretches the graph parallel to y-axis by a facor k

f (kx) stretches  the  graph by a factor 1/k parallel to x-axis

f(x + k)  moves the graph   3 units to the left.

For k negative the first one moves it k units down

for second transform negative does same transfoormation but also reflects the graph in the x axis

For the third transform negative k :- same as above but also reflects in y axis

4th transform -  negative k moves graph k units to the right
