Determine whether −9x−3y2=6 represents a function of x.

No (not a function of x)

Step-by-step explanation:

Begin by isolating the y-term to find

−9x−3y2−3y2y2=6=9x+6=−3x−2

For each value of x, multiply it by −3, add −2, and then take the square root to get the y-value. For example, if x=−6, we have

y2y2y2y=4=−3x−2=−3(−6)−2=16ory=−4

We have that if x=−6, then y=4 or y=−4. In other words, a single value of x results in more than one value of y. Since some value of x corresponds to more than one value of y, the equation does not define a function.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
