ILL MEDAL/FAN (NO DIRECT ANSWERS, PLZ) :) When the function f(x) = 3(5)^x is changed to f(x) = 3(5)^x + 22, what is the effect? There will be no change to the graph because the exponential portion of the function remains the same. The y-intercept is 22 spaces higher. The x-intercept is 22 spaces higher. All input values are moved 22 spaces to the right

    because f(x) is total y, and nothing else is changing.

    Hmmm I'm not quite sure how to explain it to you, but is x the exponent?

    ok now, notice the function transformations \(\bf \textit{function transformations} \\ \quad \\ \begin{array}{llll} \begin{array}{llll} shrink\ or\\ expand\\ by\ {\color{purple}{ A}}\end{array} \qquad \begin{array}{llll} vertical\\ shift\\ by \ {\color{green}{ D}} \end{array} \begin{array}{llll}{\color{green}{ D}} > 0& Upwards\\ {\color{green}{ D}} < 0 & Downwards\end{array} \\ % template start \qquad \downarrow\qquad\qquad\quad\ \downarrow\\ y = {\color{purple}{ 3}} (5)^{( x + {\color{red}{ C}} )} + {\color{green}{ 22}}\\ %template end \qquad\qquad \quad \uparrow \\ \qquad\begin{array}{llll} horizontal\\ shift\\ by \ {\color{red}{ C}}\end{array} \begin{array}{llll}{\color{red}{ C}} > 0 & to\ the\ left\\ {\color{red}{ C}} < 0& to\ the\ right\end{array} \end{array}\) notice the vertical shift

    It cant be c, since the x value itself is not affected by the 22.

    correct, the +22 in the function transformation, refers to a vertical shift, D > 0, means is upwards so 'y" is up bu 22 units

    up rather, by 22 units
