You are designing a binocular mount. If BC is always vertical, the binoculars will point in the same direction while they are raised and lowered for different viewers. How can you design the mount so BC is always vertical? Justify your answer.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the answer is 62.8 cubic units

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
