Answer:

-5≤x <1

Step-by-step explanation:

sqrt( x+5) / sqrt(1-x)

The numerator must be greater than zero since it is a square root

sqrt(x+5) ≥0

Square each side

x+5≥0

x≥-5

The denominator must be greater than zero (the denominator cannot be zero)

sqrt(1-x)> 0

Square each side

1-x > 0

1>x

Putting these together

-5≤x <1

The function f(x)=g(x), where f(x)=2x-5 and g(x)=x^2-6. The table below shows the process of solving using successive approximat
valkas [14]

Answer:

The positive solution is 2.4.

Step-by-step explanation:

The given functions are

f(x)=2x-5

g(x)=x^2-6

It is given that

f(x)=g(x)

2x-5=x^2-6

0=x^2-6-2x+5

0=x^2-2x-1

The quadratic formula:

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

x=\frac{2\pm \sqrt{(2)^2-4(1)(-1)}}{2(1)}

x=\frac{2\pm \sqrt{8}}{2}

x=\frac{2\pm 2\sqrt{2}}{2}

x=\frac{2(1\pm \sqrt{2})}{2}

x=1\pm \sqrt{2}

x=2.4,-0.4

Therefore the positive solution is 2.4.
