Answer:
Option B) 
is the correct option.
Step-by-step explanation:
<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>
Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.
Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.
Or we can use the cost function,
, to find which function has the least error.
By applying the above results,we find Option B is correct.
Answer:
x = 4 ± 
Step-by-step explanation:
Given
x² - 8x = 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 3 + 16
(x - 4)² = 19 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±
Answer:
C. (2,4)
Step-by-step explanation:
Answer is C. multiply by 3 - square root 5
using a^2 - b^2 = (a + b)(a - b)
Answer:
No, this matrix is singular
Step-by-step explanation:
-1*-2*3=6
2*1*-2=-4
1*2*-1=-2
So, 6+(-4)+(-2)=0 -SINGULAR-
