<span>They are the values of 'x' that make the function zero.
If you graph the function, they are the values of 'x' where the graph
crosses the x-axis.</span>
A. is your answer
you could always double check with a calculator
A COMPOSITE FUNCTION IS A COMBINATION OF TWO FUNCTIONS SUCH THAT THE OUTPUT FROM THE FIRST FUNCTION BECOMES THE INPUT FOR THE SECOND FUNCTION.
IN A COMPOSITE FUNCTION f[g(x)], SOMETIMES WRITTEN (fog) (x), THE OUTPUT OF FUNCTION G IS THE INPUT TO FUNCTION F.
Although the terms might seem intimidating, this is a simple substitution problem.
X + Y = _______
Substitute the values of X and Y in terms of w
(7w^2 + 4w - 6) + (w^2 - 11w + 13) = ______
Now all you need to do is combine like terms (terms that have the same variables raised to the same power)
8w^2 - 7w + 7
Final Answer: 8w^2 - 7w + 7
Answer:
2nd option
Step-by-step explanation:
A=wl=2.75·2.25=6.1875
2 1/4= 2.25
2 3/4= 2.75
