Which is the graph of f(x) = -3√x?<br>pls answer quickly​
k0ka [10]

Answer: the graph farthest to the right is almost correct. If you substitute values for x in the function f(x)= -3√x , the output does not match the curve on the graphs shown.

If you have a choice that includes only a curve to the right of the y- axis, that would be better.

Step-by-step explanation: Square roots of Negative x-values will result in imaginary numbers. Otherwise the graph with the curve passing through coordinates (1,-3) (4,-6) and (9,-9) is a good choice.

(And ask your teacher about the square root of negative numbers on this graph.)

What do the differences between the points (as shown on the graph) represent?
artcher [175]
The first one 7/2 represents the change in y over change in x.

For those kinds of questions I would refer to the change in y over change in x method.

Bullet 3 would work because 7/2 doesn’t result to 1. So that’s not the answer.

I hope that helps

Help me for this question please​

Answer:70 degrees and 150 degrees

Step-by-step explanation: The angles of a quadrilateral add up to 360. So the sum of the two angles is 360 - (55+ 85) = 220.

After that you can model the sum of the angles with an equation:

7x + 15x = 220

22x = 220

x = 10

then you plug in x for each angle 7(10) = 70 and 15(10) = 150
