we know that
if g(x) is the inverse of f(x)
then
g[f(x)]=x
so
![g(f(x))=\frac{1}{5} [5x-25]+5](https://tex.z-dn.net/?f=%20g%28f%28x%29%29%3D%5Cfrac%7B1%7D%7B5%7D%20%5B5x-25%5D%2B5%20)
------> this is the expression
therefore
the answer is the option
b) 1/5(5x-25)+5
Answer: C. Use a larger sample size and D. Larger confidence level
Step-by-step explanation: The information will be more accurate, as it is not right now and if there are more people then there will be a huge group of people that agree on one thing.
Answer:
Graphing
Step-by-step explanation:
1) You can graph this equation by using y=mx+b. You can replace that equation with y=3x-1.
M=3
X=x
B=-1
On a graph you would down 1 since it's negative and make a point. Then you would put a 1 under the 3 to make it a fraction. 3/1. Then you would divide 1 by 3 (1 ÷ 3). Then you would go to the right 0.33 because it's positive, and the up 1. Then you would make a second point.
This would only give you one line which wouldn't give you an intersection.
Answer:
The equation of the line normal to the curve of y=cos1/3x, where x=pi is y= 2√3 x - 10.38
Step-by-step explanation:
The equation of the normal to the curve is
Y- y1 = - 1/m (x- x1)
Where m is the gradient.
