Question

Can someone check my answer? I got C

Answer 1

\(\textit{function transformations}
\\ \quad \\

\begin{array}{llll}

\begin{array}{llll} shrink\ or\\ expand\\ by\ {\color{purple}{ A}}\end{array}
\qquad
\begin{array}{llll} vertical\\ shift\\ by \ {\color{green}{ D}} \end{array}

\begin{array}{llll}{\color{green}{ D}} > 0& Upwards\\ {\color{green}{ D}} < 0 & Downwards\end{array}
\\

% template start
\qquad \downarrow\qquad\qquad\quad\ \downarrow\\
y = {\color{purple}{ A}} \sqrt{ x + {\color{red}{ C}} } + {\color{green}{ D}}\\
%template end
\qquad\qquad \quad \uparrow \\

\qquad\begin{array}{llll} horizontal\\ shift\\ by \ {\color{red}{ C}}\end{array}

\begin{array}{llll}{\color{red}{ C}} > 0 & to\ the\ left\\ {\color{red}{ C}} < 0& to\ the\ right\end{array}
\end{array}\)

so..... should be simple enough

Answer 2

ok well let me think

Answer 3

then it would shift either way

Answer 4

NVM i feel dumb

Answer 5

either way? well, is a transformation so, yes

Answer 6

It would be D left

Answer 7

is "C" > 0 or < 0?
that is, is C positive or negative?

Answer 8

-15 = left = going negative

Answer 9

ahhh -15, that means C = -15 -15 is < 0

so C < 0, or C is negative, sooooo

Answer 10

if your going on a graph riight, then it would still be going left cause you have x before y

Answer 11

ehheh

C = -15 or C < 0, or C is negative
thus 15 units to the "right" is the transformation

Answer 12

oh so it would be opposite

Answer 13

yes, for the "x" or horizontal shift is a bit counterintuitive, yes
you'd expect negative to go to the left but goes the other way
that's true only for the horizontal shift :)

Answer 14

its weird though how'd it would go right.. I would of never of gotten A without your help!

Answer 15

thank you for the help
