Answer: Second option: (4,0) and (-9,0)
f(x)=x^2+5x-36
The x-intercepts of the graph of a function f(x) are the values of the variable x that makes f(x)=y equal to zero. To find these values we only have to equal f(x)=y to zero:
f(x)=y=0
x^2+5x-36=0
Factoring the polynomial:
(x+9)(x-4)=0
Using that if a b=0, then: a=0 or b=0
with a=x+9 and b=x-4
x+9=0 or x-4=0
Solving for x:
x+9-9=0-9 or x-4+4=0+4
x=-9 or x=4
Then the x-intercepts are the poitns (x,y)=(x,0):
(4,0) and (-9,0)

Hello there!
Knowing that you have a swimsuit of an original price of $20.30 that is discounted 65%, you can find the price of the swimsuit after the discount by first finding 65% of your original price.
To find 65% of your original price, multiply 65% to 20.30:
0.65*20.30
=13.195
Now, subtract this amount from your original price:
20.30-13.195
=7.105
Finally, round to the nearest cent to get $7.11 dollars as your final answer.
Hope this helps and have a marvelous day! :)
