Hello there!
To find the zeroes or the roots of a function, you just need to set the function equal to 0 then solve for x
f(x) = 2x² - 8x - 10
Set function equal to 0
2x² - 8x - 10 = 0
Now we can factorize the left side
2(x + 1)(x - 5) = 0
Then set factors equal to 0
x + 1 = 0 or x - 5 = 0
x = 0 - 1 or x = 0 + 5
x = -1 or x = 5
Thus,
The roots are -1 and 5
Let me know if you have any questions. As always, it is my pleasure to help students like you~!

choice C
Answer:
D. Mathematical expressions for the relationships
Step-by-step explanation:
Quantitative analysis also called QA for short is the technique that tries to understand behaviour by using mathematical and statistical modeling, measurement and research. A quantitative analyst aims to represent a given reality in terms of numerical value. This can be achieved by using mathematical formulas and expressions to explain the relationships that exists between the variables. The data analyzed are usually gotten from polls and questionnaires or in general, well structured research instruments.
First align the decimal points and the numbers, then add the extra 0's if needed. Lastly, add and the total answer is 14.225.
Answer:
Step-by-step explanation:
0 and 1, both the values of the graphs of the functions are equal at both 0 and 1
