The ranges values of the function f(x) are: {-89,-9,7} - Option D.
<h3>Domain and Range</h3>
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.
While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
Here, you need to replace the domain values in the given equation.
f(x)=-2x²+9
f(x)=-2*(-3)²+9
f(x)=-2*9+9
f(x)=-18+9=-9
- For x=1
- f(x)=-2*(1)²+9
- f(x)=-2*1+9
- f(x)=-2+9=7
- For x=7
- f(x)=-2*(7)²+9
- f(x)=-2*49+9
- f(x)=-98+9=-89

Answer:
Yes, because 9 is in the hundreths place and 3 is in the tenths
Step-by-step explanation:
Answer:
240÷48=5 no of buses needed, use division
Answer:
133.04 is the approximate answer
Answer: An equation is *629 = n - 99. The geometry book has 728 pages*
Step-by-step explanation: The Algebra book has 99 pages LESS than the geometry book, in other words, the geometry book has 99 pages MORE than the Algebra book. This equation can be used to find the answer. I’m afraid 530 is not the answer.
Hope this helps! :)
