Use the given domain to find the range of function:

f(x)=−2x2+7, d={2, −3, 0}

will mark brainliest

The range of the function is {-1 , -11 , 7}

Step-by-step explanation:

- The range is the resulting values of y we get after substituting all

   the possible values of x

- The domain of the function is the values of x

- The range of the function is the values of y corresponding to the

   values of x ⇒ [y = f(x)]

∵ f(x) = -2x² + 7

∵ The domain D = {2 , -3 , 0}

- We need to find the values of f(x) corresponding to x = 2 , x = -3

   and x = 0

- Substitute the values of x in f(x)

∵ x = 2

∴ f(2) = - 2(2)² + 7

∴ f(2) = -2(4) + 7

∴ f(2) = -8 + 7

∴ f(2) = -1

∵ x = -3

∴ f(-3) = - 2(-3)² + 7

∴ f(-3) = -2(9) + 7

∴ f(-3) = -18 + 7

∴ f(-3) = -11

∵ x = 0

∴ f(0) = - 2(0)² + 7

∴ f(0) = -2(0) + 7

∴ f(0) = 0 + 7

∴ f(0) = 7

The range of the function is {-1 , -11 , 7}

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
