Answer:
B
Step-by-step explanation:
The zeros ( where the graph crosses the x- axis ) are x = 2 and x = 6
The corresponding factors are (x - 2) and (x - 6) and the equation is the product of the factors, so
y = (x - 2)(x - 6) ← expand using Foil
y = x² - 8x + 12 → B
NOOOOO I AM WRONG GGGGGGGG
Answer: SECOND OPTION.
Step-by-step explanation:
1. You must subtract the function f(x) and g(x), therefore, you obtain:
![(f-g)(x)=x-3-(-0.5x)\\(f-g)(x)=x-3+0.5x\\(f-g)(x)=1.5x-3](https://tex.z-dn.net/?f=%28f-g%29%28x%29%3Dx-3-%28-0.5x%29%5C%5C%28f-g%29%28x%29%3Dx-3%2B0.5x%5C%5C%28f-g%29%28x%29%3D1.5x-3)
2. When you graph
, you obtain the graph shown attached.
3. As you can see, the interval in which the value
is negative is:
(-∞,2)
Therefore the answer is the second option.
Answer:
The center is (5, -4)
Radius 9
Step-by-step explanation:
![Raduis: \sqrt{81} =9\\](https://tex.z-dn.net/?f=Raduis%3A%20%5Csqrt%7B81%7D%20%3D9%5C%5C)
Center is just the opposite in the formula
Answer:
a) 6
b) 6i
c) 6i
d) -6
Step-by-step explanation:
We are going to write down the numbers as a product of prime numbers and then proceed to solve:
Note: Remember that i = √-1 and that i²= -1
a) √9(√4)
√3² × √2² = 3 × 2 = 6
Thus, the answer is 6
b) √9 ×√-4
√3² x i√2² = 3 x 2i = 6i
Thus, the answer is 6i
c) √-9.√4
i√3² × √2² = 3i x 2 = 6i
Thus the answer is 6i
d) √-9.√-4
i√3² × i√2²
3i x 2i = -6
Thus the answer is -6
