Which of the following could be an example of a function with a range (-∞,a] and a domain [b, ∞) where a < 0 and b < 0?

aleksandrvk [35]

Answer:

$f(x) = - \sqrt{x - b} + a$

Step-by-step explanation:

We have to choose the function from the given options which have a range (-∞, a] and a domain [b,∞) where a < 0 and b < 0.

I think the function is $f(x) = - \sqrt{x - b} + a$ ......... (1)

Here, x - b must be greater than equal to zero for the function to be real.

Hence, x - b ≥ 0

⇒ x ≥ b

So, the domain is [b, ∞).

Now, putting x = b in the equation (1),we get f(x) = a and putting x = ∞, we get f(x) = - ∞.

Therefore, the range of the function is (-∞, a]. (Answer)

Answer:

a) P [Z < 5.79] = 7.49 %

b) P [ Z > 7.46 ] = 82.38 %

c) P [ Z > 6.65 ] = 91.68 %

Step-by-step explanation:

Normal Distribution

Population Mean μ₀ = 6.8 cm

Standard Deviation of population σ = 0,7 cm

a) P [ Z < 5.79 ] = ??

z value ?

z = ( 5,79 - 6,8 ) / 0,7 ⇒ z = - 1.01 / 0,7 ⇒ z = - 1.442

From z table we get:

z = - 1.442 ⇒ P [Z < 5.79] = 0.0749 or

P [Z < 5.79] = 7.49 %

b) P [ Z > 7.46 ]

z = ( 7.46 - 6,8 ) / 0,7 ⇒ z = 0.66 / 0.7 ⇒ z = 0.942

From z table

P [ Z > 7.46 ] = 0.8238 or P [ Z > 7.46 ] = 82.38 %

c) P [ Z > 6.65]

z = ( 6.65 - 6.8 ) / 0.7 ⇒ z = - 0,15 / 0.7 ⇒ z = - 0.214

From table we get area between 6.65 and the mean, therefore we have to add ( 0.5 ) half of total area

Then from z table

z = - 0,214 ⇒ 0,4168

Then P [ Z > 6.65 ] = 0,4168 + 0.5

P [ Z > 6.65 ] = 0.9168 or

P [ Z > 6.65 ] = 91.68 %

P [ Z > 6,65 ] = 0,5 +
