Answer:
3³
Step-by-step explanation:
Using the rule of exponents
= 
Given

= 
= 3³
B is correct.
A. 5(x-2)= 5x-10
B. 4(x+3)= 4x + 12
C. 3(x+1)= 3x+3
D. 2(x+7) = 2x + 14
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:
(0,4),(3,0)
slope = (0 - 4) / (3 - 0) = -4/3
y = mx + b
slope(m) = -4/3
ur y int is when x = 0....so it is 4
and in y = mx + b form, the slope is in the m position and the y int is in the b position
so ur equation is : y = -4/3x + 4 <==
