Which function has zeros at x = −2 and x = 5?

f(x)=

Step-by-step explanation:

If a function has two zeros x=a and x=b then function can be written as

similarly if a function has two zeros at x = −2 and x = 5

then function can be written as

Therefore f(x)= is required function

f(x) = x²-3x-10  is the answer.

Step-by-step explanation:

We have to find the function that has zeros at x = -2 and x=5 .

Function that has two zeros is of the form :

(x-c)(x-d) = 0

If the function has two zeros at x = -2 and x=5 then it is of the form:

(x-(-2))(x-5)=0

(x+2)(x-5) = 0

(x+2)(x-5) = 0

x²-5x+2x-10 =0

x²-3x-10 = 0 is the  function has zeros at x = −2 and x = 5.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
