Question 1 of 2
1. Question
Find the graph for `y=(x 2)^3+3` by using `y=x^3`.
Correct
Great Work!
Incorrect
Help VideoHorizontal and vertical translations (shifts) of cubic functions are written in the form `y=(xcolor(red)(h))^3 +color(blue)(c)` where the point `(color(red)(h),color(blue)(c))` is the inflection point of the function.`color(red)(h)` is a shift to the right and `color(blue)(+c)` is a shift upwards.`(h) \ bb(rarr)` Shift Right`(+h) \ bb(larr)` Shift Left`(c) \ bb(darr)` Shift Down`(+c) \ bb(uarr)` Shift UpTo obtain the graph of `y=(x color(red)(2))^3+color(blue)(3)`, first sketch the function `y=x^3`.Sketch the function `y=x^3`. Remember the formula `y=(xh)^3 +c` when applied to `y=x^3` (can be rewritten as `y=(xcolor(red)(0))^3+color(blue)(0)`) has its inflection point at `(color(red)(0),color(blue)(0))`.Using the formula `y=(xh)^3 +c` for horizontal and vertical translations (shifts) and remembering that the point `(h,c)` is the inflection point of the function, the inflection point for `y=(x color(red)(2))^3+color(blue)(3)` is `(color(red)(2),color(blue)(3))`.Sketch the curve for `y=(x color(red)(2))^3+color(blue)(3)` through its inflection point `(color(red)(2),color(blue)(3))` following the same shape as `y=x^3`.

Help VideoHorizontal and vertical translations (shifts) of quadratic functions are written in the form `y=(xcolor(red)(h))^2 +color(blue)(c)` where the point `(color(red)(h),color(blue)(c))` is the vertex of the function.`color(red)(h)` is a shift to the right and `color(blue)(+c)` is a shift upwards.`(h) \ bb(rarr)` Shift Right`(+h) \ bb(larr)` Shift Left`(c) \ bb(darr)` Shift Down`(+c) \ bb(uarr)` Shift UpTo obtain the graph of `y=x^2 – 6x + 11`, first sketch the function `y=x^2`.Sketch the function `y=x^2`. Remember the formula `y=(xcolor(red)(h))^2 +color(blue)(c)` when applied to `y=x^2` (can be rewritten as `y=(xcolor(red)(0))^2+color(blue)(0)`) has its vertex at `(color(red)(0),color(blue)(0))`.Then rewrite `y=x^2 – 6x + 11` in the standard form by completing the square.`y=(x^26x+9)9+11``y=(x 3)^2+2`.Remember the standard form is `y=(xh)^2 +c`.Using the formula `y=(xh)^2 +c` for horizontal and vertical translations (shifts) and remembering that the point `(h,c)` is the vertex of the function, the vertex point for `y=(x color(red)(3))^2+color(blue)(2)` is `(color(red)(3),color(blue)(2))`.Sketch the curve for `y=(x color(red)(3))^2+color(blue)(2)` through its vertex point `(color(red)(3),color(blue)(2))` following the same shape as `y=x^2`.
