Which equation is the inverse of y = 100 – x2? y = plus-or-minus StartRoot 100 minus x EndRoot
y = 10 plus-or-minus StartRoot x EndRoot
y = 100 plus-or-minus StartRoot x EndRoot
y = plus-or-minus StartRoot x minus 100 EndRoot

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

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
