Answer: 275 + +20.2 = 296
275 + - 20. = 255.
Step-by-step explanation:
275 + + 20.2 (
= 275 + 0.8 + 20.2
= 275.8 + 20.2 = 296
275 + - 20.2
= 5 + 0.8 - 20.2 ( = 0.8)
= 275.8 - 20.2 = 255.

Answer:
With
So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
Step-by-step explanation:
For this case we know the following function:
We can begin the zeros or the values where the function is 0 like this:
And solving for x we got:
Now we can rewrite the expression like this:
And we can find the position for the vertex at x with this formula:
With
And replacing we got:
And then with the coordinate of x for the vertex we can find the coordinate of y replacing the value of x obtained for the vertex.
Then we can find the intercept using the value of x=0 and replacing into the function we got:
So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
