Answer:

x-intercept → (-4, 0)

y-intercept → (0, -2.44)

Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

Given function is f(x) = -\sqrt[3]{(x+3)}-1

For x-intercept,

-\sqrt[3]{(x+3)}-1=0

-\sqrt[3]{(x+3)}=1

\sqrt[3]{(x+3)}=-1

(x + 3) = -1

x = -4

Therefore, x-intercept → (-4, 0)

For y-intercept,

Substitute x = 0 in the function.

f(x) = -\sqrt[3]{(0+3)}-1

     = -\sqrt[3]{3}-1

     = -1.44 - 1

     = -2.44

Therefore, y-intercept → (0, -2.44)

Domain: This function is defined for all real values of x.

Therefore, Domain: (-∞, ∞)

Range: Since this function is defined for all real values of x, we will get a distinct output value for every distinct input values.

Therefore, Range: (-∞, ∞)

Can someone help me with this question
maria [59]

Step-by-step explanation:

1/5 + 3/5 = 3/5 + 1/5 = 4/5

I am not sure what your teacher wants to see on the right side of the second equation.

it would be the whole equation again :

4/5 = 1/5 + 3/5 = 3/5 + 1/5

What is the first step in writing f(x) = 6x2 + 5 – 42x in vertex form?
Marina CMI [18]
The first step to getting this in vertex form would be to put this in proper standard form. This is so that you can split the middle term which is a step of completing the square.
