If you answer right ill give brainliest, : )

replace f(x) with y

.

y=x2+x−30

To find the roots of the equation, replace y

with 0

and solve.

0=x2+x−30

Rewrite the equation as x2+x−30=0

x2+x−30=0

Factor x2+x−30

using the AC method.

(x−5)(x+6)=0

Set x−5

equal to 0 and solve for x

x=5

Set x+6

equal to 0 and solve for x

x=−6

The solution is the result of x−5=0

and x+6=0

x=5,−6

Hope this helps!

answdf

step-by-step explanation: bcuz d is right

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
