Answer:
The parent function that can be used to graph is:
Step-by-step explanation:
We are asked to find the parent function that can be used to graph the function f(x) which is given as:
We know that from the given options the parent function that best represents the relationship or that can be used to graph the function f(x) is:
since the function is just a transformation of the parent function the transformation that is applied is a combination of a dilation with a scale factor '-9' and a translation '-5' units to the left and a reflection along 'x' axis.
Hence, the parent function is:
Remember that the quadratic formula is: .
stands for the coefficient of the first term, the one associated with the
,
stands for the coefficient of the second term, the one associated with
, and
stands for the value of the constant.
In , our a-value is 1, our b-value is also 1, and our c-value is also 1.
Thus, when we plug in our values into our formula, we get the answer:
Simplifying this answer using , we get our final answer of:
