Answer:
and ![x = 0.381](https://tex.z-dn.net/?f=x%20%3D%200.381)
Step-by-step explanation:
![y = \sqrt x\\](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%20x%5C%5C)
![y = x - 1](https://tex.z-dn.net/?f=y%20%3D%20x%20%20-%201)
Required
y, when they are equal.
To do this, we set them to another
![\sqrt{x} = x - 1](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%3D%20x%20-%201)
Square both sides
![x = (x - 1)^2](https://tex.z-dn.net/?f=x%20%20%3D%20%28x%20-%201%29%5E2)
Expand
![x = x^2 - 2x + 1](https://tex.z-dn.net/?f=x%20%3D%20x%5E2%20-%202x%20%2B%201)
Collect like terms
![x^2 -x-2x+1 = 0](https://tex.z-dn.net/?f=x%5E2%20-x-2x%2B1%20%3D%200)
![x^2 - 3x + 1 = 0](https://tex.z-dn.net/?f=x%5E2%20-%203x%20%2B%201%20%3D%200)
Using quadratic formula
and ![x = 0.381](https://tex.z-dn.net/?f=x%20%3D%200.381)
What do you need help with?
I'll help you in the comments of this questions. need time to work it out.
Quadratic functions can be written in three forms. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring. ... The parameter is the y-intercept, while the parameter is the slope of the tangent at 0.
