Transformations??? I don't understand State the various transformations applied to the base function f(x)=|x| to obtain a graph of the functiong(x) = |x + 1| - 2.
(a.)Horizontal shift of 1 unit to the left and a vertical shift upward of 2 units. (b.)Horizontal shift of 1 unit to the left and a vertical shift downward of 2 units. (c.)Horizontal shift of 1 unit to the right and a vertical shift downward of 2 units. (d.)Horizontal shift of 1 unit to the right and a vertical shift upward of 2 units.
SHIFTS: \(\large\color{black}{ f(x)=\left| x \right| ~~~~~\bf{\rightarrow}~~~~~f(x)=\left| x \color{blue}{ -~\rm{c} }\right| }\) \(\large\color{blue}{ ~\rm{c} }\) units to the right. \(\large\color{black}{ f(x)=\left| x \right| ~~~~~\bf{\rightarrow}~~~~~f(x)=\left| x \color{blue}{ +~\rm{c} }\right| }\) \(\large\color{blue}{ ~\rm{c} }\) units to the left. \(\large\color{black}{ f(x)=\left| x \right| ~~~~~\bf{\rightarrow}~~~~~f(x)=\left| x \right| \color{blue}{ +~\rm{c} }}\) \(\large\color{blue}{ ~\rm{c} }\) units to up. \(\large\color{black}{ f(x)=\left| x \right| ~~~~~\bf{\rightarrow}~~~~~f(x)=\left| x \right| \color{blue}{ -~\rm{c} }}\) \(\large\color{blue}{ ~\rm{c} }\) units to down.
your function is supposed to be, \(\large\color{black}{ f(x)=\left| x +1\right|+2 }\) is that correct?
or g(x)... f(x), g(x), h(x) ... makes no difference here.
it's supposed to be f(x) = |x + 1| - 2, not add 2 I messed up something else though, forgot to include the base function in original question, changing that now
\(\large\color{black}{ f(x)=\left| x +1\right|-2 }\)
sure...
just added the base function to original question, and changed the equals to subtract 2
sure:)
Do you understand tyhe rules I posted?
no
wait hang on they're starting to make sense
so the units will move to the left?
how many units to the left? which one is the shift to the left, the +1 on the inside, or the -2 on the outside?
1 unit to the left, the shift to the left is the +1 on the outside
so far my answer choices are either a or b?
yes that is correct. the +1, moves the f(x) 1 unit left.
Now, the "-2" part on the outside, is a shift where, and by how many units?
it's a downward shift because subtracting downward on a coordinate grid? and 2 units
yes. you are going 2 units down.
So my answer is B, Horizontal shift of 1 unit to the left and a vertical shift downward of 2 units.?
So g(x), the new function, is 1 units to the left and 2 units down, from the (initial) f(x). yes, B....
thank you!!
I would write these rules somewhere on a paper so that you rememeber them. Because you will need them ....
i will
not only in algebra, but even on in calc1:) .... you welcome!
