Write a quadratic function whose zeros are -2 and -10

f(x) = x^2 + 12x + 20

Step-by-step explanation:

What is meant is that write a function that when - 2 is put in for x, the function goes to 0.

More formally f(-2) = 0.

So the function you want is f(x) = y = (x + 2)(x + 10) which is

f(x) = x^2 + 10x + 2x + 20

f(x) = x^2 + 12x + 20

Now  put - 2 into this function.

f(-2)= (-2)^2 + 12(-2) + 20

f(-2) = 4 - 24 + 20

f(-2) = 4 + 20 - 24

f(-2) = 0

I'll leave you to do the same thing with - 10

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
