Answer:
5 years
Step-by-step explanation:
(x+15)=4x
15=4x-x
15=3x
5=x
A "solution" is where the graph crosses the
x-axis so while the quadratic has no real solutions, the straight line passing through it does as it intersects the x-axis at x=-2.
Hope this helps! :)
Consider f(x)=y.

Simplify the equation f(x)=y to obtain the value of x in terms of y.

So inverse of function is,
