Question

Find a cubic function with the given zeros.

-2, 5, -6

Answer 1

f(x) = x3 + 3x2 + 28x - 60
f(x) = x3 - 3x2 - 28x - 60
f(x) = x3 + 3x2 - 28x - 60
f(x) = x3 + 3x2 - 28x + 60

Answer 2

State the vertical asymptote of the rational function.

f(x) = quantity x minus four times quantity x plus nine divided by quantity x squared minus one

x = 1, x = -1
None
x = 4, x = -9
x = -4, x = 9

Answer 3

(x +2) (x - 5) ( x + 6)


[ x^2 + 2x - 5x - 10 ] [ x + 6 ]
[ x^2 - 3x - 10] [ x + 6 ]
x [ x^2 - 3x - 10 ] + 6 [ x^2 - 3x - 10 ]
x^3 - 3x^2 - 10 x + 6x^2 - 18x - 60 combine like terms
x^3 + 3x^2 - 28x - 60

Answer 4

awesome thanks can you help me with 3 more?

Answer 5

I'll try....

Answer 6

State the vertical asymptote of the rational function.

f(x) = quantity x minus four times quantity x plus nine divided by quantity x squared minus one

x = 1, x = -1
None
x = 4, x = -9
x = -4, x = 9

Answer 7

i cant find this one

Answer 8

\[f(x)=\frac{ (x−4)(x+9) }{ (x^2−1) }\]
To find vertical asymptote, set the denominator to zero then find 'x'
\[x^2-1=0\]
\[x^2=1\]
\[x=1,x=-1\]

Answer:
\[x=1,x=−1\]
