4. A rectangular building is to be placed on a lot that measures 30 m by 40 m. The building must be placed in the lot so
that the width of the lawn is the same on all four sides of the building. Local restrictions state that the building cannot
occupy any more than 50% of the property. What are the dimensions of the largest building that can be built on the
property?

1; 35 is the ratio

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
