It's simple, you first do -b/2a, (This is how the equation is supposed to go: ax^2+bx+c) Therefore, to this answer, it is -1. Now this answer will be you x point, and you use that to find the vertex by putting -1 as b. You have two choices that are correct, so eliminate those who's x isn't -1. Finally, put -1 as b, which would end up as -1^2+2(-1)-35, and when you simplify it, you end up with -36, making D the answer

Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
<u>Given the following data;</u>
Experimental value = 4.5cm
Theoretical value = 4.8cm
<em>Substituting into the equation, we have;</em>
Percent error = 6.25%
