Mathematics
1 answer:
BigorU [14]3 years ago
4 0

Answer:

Step-by-step explanation:

a)

f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.

What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.

so f(0) = 0 + 4 = 5

b)

By similar reasoning:

f(6) = 8

because 5 <= 6 < 7

Answer:

b.  \sqrt[3]{4x+2}

Step-by-step explanation:

f(x) = ( x^3-2) /4

y = ( x^3-2) /4

Exchange x and y

x = ( y^3-2) /4

solve for y

Multiply each side by 4

4x = 4( y^3-2) /4

4x = y^3 -2

Add 2 to each side

4x+2 = y^3

Take the cubed root of each side

( 4x+2) ^ (1/3) = y^3 ^(1/3)

( 4x+2) ^ (1/3) =y

olga2289 [7]

Answer:

D

Step-by-step explanation:

When the function or the coefficient in this case 1/4x^2 is positive it means it's opening up like a u, meaning all the values will be bigger than the C term or -5 in this case.
