The given function is
f(x)= 0.2 x²
Since f(x) will be defined for all real values of x.
So, Domain of f(x) will be ( x| x is a real number.)→This is set builder notation.
Finding the inverse of f(x):
y = 0.2 x²
→ x²= 5 y
→x = 
→ → Inverse of f(x)
Replacing x by y and y by x,we get inverse of the given function
y = 
→ →Domain x ≥ 0, x∈[0,∞]
Graph of function and its inverse are shown below.
To find the median, we must order the numbers.
12,12,13,13,14,15,16,17,18,19
Now see which one is in the middle.
We are stuck between 14 and 15, so what is between those?
14.5 is between 14 and 15, so that is the median.
Answer: 14.5 is the median
Answer: 17,147
Step-by-step explanation:
A square should have 4 lines of symmetry
Answer:
The scale factor is 2.
Step-by-step explanation:
Take the vertical sides of the 2 triangles.
Their length is 3 and 6 so the scale factor is 6/3 = 2.
Also we see than the horizontal lines are in the same ratio 4 : 2 = 2:1.
