Answer: The value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6
Step-by-step explanation:
Since we have given that
y varies directly as x.
If y = 18, when x = 5.
So, we need to find the value of y when x is 11.
According to question, we get that
![\dfrac{y}{x}=\dfrac{18}{5}=\dfrac{y}{11}\\\\18\times 11=5y\\\\198=5y\\\\\dfrac{198}{5}=y\\\\y=39.6](https://tex.z-dn.net/?f=%5Cdfrac%7By%7D%7Bx%7D%3D%5Cdfrac%7B18%7D%7B5%7D%3D%5Cdfrac%7By%7D%7B11%7D%5C%5C%5C%5C18%5Ctimes%2011%3D5y%5C%5C%5C%5C198%3D5y%5C%5C%5C%5C%5Cdfrac%7B198%7D%7B5%7D%3Dy%5C%5C%5C%5Cy%3D39.6)
Hence, the value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6

Consider, pls, this option:
a) h(-x)=-(7x⁷-7x);
b) -h(x)=-(7x⁷-7x);
c. h(-x)=-h(x), yes;
d. this function is odd.
The domain is a discrete set. So we will have a discrete range.
The range is a set containing:
f(-2)=-11
f(-1)=-9
f(0) = -7
f(1) = -5
f(2) = -3
Range = {-11,-9,-7,-5,-3}
