Consider functions fand g.

Sauron [17]

The value of (gof)(4) is 9 if the function f(x) is f(x) = -x³, and function g(x) is g(x) = |1/8x-1| option (B) is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = -x³

$\rm g(x) = |\dfrac{1}{8}x-1|$

Plug x = 4 in the f(x)

f(4) = -4³ = -64

Plug the above value in the g(x)

$\rm g(x) = |\dfrac{1}{8}(-64)-1|$

g(f(4)) = |-8-1| = |-9| = 9

Thus, the value of (gof)(4) is 9 if the function f(x) is f(x) = -x³, and function g(x) is g(x) = |1/8x-1| option (B) is correct.

X^2 + 4y^2 =100; 4y - x^2 = -20

deff fn [24]

$x^2+4y^2=100\implies x^2=100-4y^2$
$\implies 4y-(100-4y^2)=-20$
$\implies 4y^2+4y-80=0$
$\implies y^2+y-20=0$
$\implies (y-4)(y+5)=0$
$\implies y=4,y=-5$

When $y=4$ , you have

$4(4)-x^2=-20\implies x^2=36\implies x=\pm6$

When $y=-5$ ,

$4(-5)-x^2=-20\implies x^2=0\implies x=0$

So there are three solutions, $(x,y)\in\{(6,4),(-6,4),(0,-5)\}$ .
