The number of roots of a quadratic function can be determined from its discriminant.

If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.

The discriminant can be calculated as:

Disc = b² - 4ac

For the given equation:

Disc = 9 - 4(2)(1) =1

Since the value of discriminant is positive, the function will have two distinct roots.

So, the answer to this question is option B

If f(x)=2x and g(x)= 1/x, what is the domain of (f*g) (x)
postnew [5]

Answer:

The domain of (f*g) (x) is the set of all real numbers; ( -∞, ∞)

Step-by-step explanation:

(f*g) (x) simply means we obtain the product of f(x) and g(x). We are given that;

f(x)=2x

g(x)= 1/x

(f*g) (x) = f(x) * g(x)

(f*g) (x) = 2x * 1/x = 2

This is a horizontal line defined everywhere on the real line. The domain of  (f*g) (x) is thus ( -∞, ∞)

Lyrx [107]

<u>Answer</u>

Time taken to paint the fence by Marco  and Jaylyn is 2.72 hours

Heading can be given to this is work per hour

<u>Explanation</u>

Macro 6 hours to paint fence by himself

Therefore his 1 hour work = 1/6

Jaylyn 5 hours to paint the same fence by herself

Therefore 1 hour work of  Jaylyn  = 1/5

Together 1 hour work = 1/6 + 1/5 = 11/30

Therefore time taken to paint the fence together by them = 30/11 = 2.72 hours
