Answer:

  • A.  f(x) = (x - √2)(x + √3)

Step-by-step explanation:

Leading coefficient is 1, multiplicity is 1, roots are √2 and -√3. It means the function is the product of two binomials.

<u>The function with the roots of a and b is:</u>

  • f(x) = (x - a)(x - b)

<u>Substitute and and b:</u>

  • f(x) = (x - √2)(x - (-√3)) ⇒
  • f(x) = (x - √2)(x + √3)

Correct choice is A

Answer:

for a

f(x)=(x-√2)(x+√3)

f(x)=(x-√2)(x-(-√3))

it has coefficient of 1 and roots √2 and -√3 with multiplicity 1

for second

f(x)= (x + √2)(x-√3)

f(x)= (x -( √2))(x-√3)

it has coefficient of 1 and but not roots √2 and -√3 with multiplicity 1

for third

f(x)=(x-√2)(x-√2)(x-√3)(x-√3)

f(x)=(x-√2)²(x-√3)²

it has coefficient of 1 and but not roots √2 and -√3 with multiplicity 1

for forth

f(x)=(x-√2)(x+√2)(x-√3)(x+√3)

f(x)=(x²-2)(x²-3)it has coefficient of 1 and but not roots √2 and -√3 with multiplicity 1

So

<u>f(x)=(x-√2)(x-(-√3))</u><u> </u><u>i</u><u>s</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>

The Venn diagram shows the results of two events resulting from rolling a number cube.
lorasvet [3.4K]

Answer:

Option B.

Step-by-step explanation:

From the given venn diagram it is clear that

A={1,2}

B={1,2,3,4,5,6}

A\cap B={1,2}

Since the intersection of A and B is non-empty, therefore by conditional probability

P(B|A)=\dfrac{P(A\cap B)}{P(A)}

P(B|A)\cdot P(A)=P(A\cap B)

P(A\cap B)=P(B|A)\cdot P(A)

Therefore, the correct option is B.
