Answer:

-37

Step-by-step explanation:

for the first equation to equal 4 the x must equal -6.

because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.

So now plug -6 into the new problem so now it is

5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!

hope this helps :)

F(x)=-2x+1; {-2,0,2,4,6} Find the range of the function for the given domain.

3241004551 [841]

Answer:

For the domain indicated, the range is {-11, -7, -3, 1, 5}

Step-by-step explanation:

Given the indicated domain of f(x) you have to replace the values in the function to find the range (the "y" values of the function).

f(-2) = 5

f(0) = 1

f(2) = -3

f(4) = -7

f(6) = -11.

So the range for this domain is {-11, -7, -3, 1, 5}
