Using the quadratic formula we can see the roots are:
3 and -3
Answer:
The answer to your question is below
Step-by-step explanation:
See the graph below.
I recommend you to evaluate the function when x = (-1, 0, 1, 2, 3, and 4) to get the values of y.
Then, in the graph we look for the points where the line crosses the x-axis, these points will be the roots.
In the graph we observe that the root are x = 1 and x = 2.4
Answer:
8. Not a function, the first three are of the same pattern but not the last two
9. Not a function, each input should have only 1 output or two inputs could have one output.
The answer would be
y-5=2(x-5)
then to convert to slope intercept it would be
y=2x-5
