What’s the number then I could help
Answer:
The range of g(x) = -2x + 33 is D. (Negative infinity, positive infinity)
Step-by-step explanation:
The function g(x) is a linear line, so all values of x are included in the domain. If all values of x in the domain works, then there are infinite amount of values for both x and y. Therefore, your answer is D.
Completing the square
alrighty
minus 31 both sides
x²+12x=-31
take 1/2 of the linear coefient and square it
12 is the linear coefient
12/2=6, (6)²=36
add that to both sides
x²+12x+36=36-31
factor perfect square trinomial
(x+6)²=5
square root both sides, remember to take positive and negative root
x+6=+/-√5
so what you want to write is
x+6=√5 and
x+6=-√5
the solutions
minus 6 both sides
x=-6+√5 and -6-√5
