Answer:
191
Step-by-step explanation:
The amount spent for a single text: 177/17,7=0,1
x×0,1=19,1
x=19,1/0,1
x=191
Question:
Solution:
Let the function
![y=f(x)\text{ = }\sqrt[]{x}-9](https://tex.z-dn.net/?f=y%3Df%28x%29%5Ctext%7B%20%3D%20%7D%5Csqrt%5B%5D%7Bx%7D-9)
Now remember the following rule:
To graph y = f(cx)
if 0 < c < 1 , stretch the graph of y = f(x) horizontally by a factor of 1/c.
Thus, applying this to the given function, with c = 3, we can conclude that the correct answer is:
