The function is differentiable for:
x² - 4 x - 5 ≠ 0
x² - 5 x + x - 5 ≠ 0
x ( x - 5 ) + ( x - 5 ) ≠ 0
( x - 5 ) ( x + 1 ) ≠ 0
x ≠ 5 and x ≠ - 1
Answer: x ∈ R \ { -1, 5 }

stira [4]
X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
X1 = (8-10)/2 = -1
X2= (8+10)/2= 9

Find the value of x with the steps
Mrrafil [7]
Two sides are same so that would be isosceles triangle. So then you would add up all angles and get this equation: 180 = 38 + x + x

2x = 142

x = 71

So the value of x is 71.

The formula for the distance, d, an accelerating car can travel is d = 5.6t square. how many minutes, t, doe the car take to tra
Likurg_2 [28]
Your distance(d) is 1,814.4
1814.4 m = 5.6t square
then you square root 5.6t
\sqrt{1814.4} = \sqrt{ {5.6t}^{2} }
the square root eliminates the square
\sqrt{1814.4} = 5.6t
you square root 1,814.4 m
42.6 = 5.6t
(I rounded 42.6) then divide 42.6 by 5.6
7.6 = t
(I rounded 7.6)
