Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is . Once we have the slope, we can use any given point to plug in to find the y-intercept.
We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.
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.
