PLEASE EXPLAIN: h(x) = sqrt(4-x^2), find the domain and range.

1 answer:

8 0

H(x), or the range of this function, must be y >= 0, as you can never get a negative when square rooting any number.

For the domain, x cannot exceed -2 or 2, as this would mean we'd be finding the square root of a negative number, which can't happen without getting in to imaginary numbers. Thus, the domain must be -2 <= x <= 2.

The weight of Jill’s fish is $56{\text{ ounces}}$ and the weight of parakeet is $\boxed{{\mathbf{7 ounces}}}$ .

Further explanation:

Given:

It is given that the weight of Jill’s fish is 8 times as much as her parakeet. The total weight of fish and parakeet is .

Step by step explanation:

Step 1:

Consider $x$ as the weight of parakeet.

It is given that the weight of Jill’s fish is 8 times of the weight of parakeet.

Therefore, the weight of Jill’s fish can be expressed as $8x$ .

Step 2:

The total weight of fish and parakeet is $63{\text{ ounces}}$ .

Now make an equation for the total weight of fish and parakeet both as,

$x + 8x = 63$

Now solve the equation $x + 8x = 63$ to obtain the value of $x$ .

$\begin{aligned}x + 8x &= 63 \\9x &= 63 \\\end{aligned}$

Now divide the resultant equation by 9 to obtain the value of $x$ .

$\begin{aligned}\frac{9}{9}x&= \frac{{63}}{9} \\x &= 7 \\\end{aligned}$

Therefore, the weight of parakeet is $7{\text{ ounces}}$ .

Step 3:

Now find the weight of Jill’s fish that is $8x$ where $x$ is the weight of parakeet.

Now substitute the value of $x = 7$ in the expression $8x$ to obtain the weight of Jill’s fish as,

$\begin{aligned}{\text{weight of fish}} &= 8x \\& = 8 \times 7 \\&= 56 \\\end{aligned}$

Therefore, the weight of Jill’s fish is $56{\text{ ounces}}$ and the weight of parakeet is $7{\text{ ounces}}$ .
