Which function has the given properties below? the domain is the set of all real numbers. one x-intercept is ( pi/2 , 0) the maximum value is 3. the y-intercept is (0,-3)

The function could be y= - 3 cos x

Solution:

One x-intercept is (pi/2,0): We can use a trigonometric function like cosine that has x-intercept (pi/2,0).

The domain of the cosine function is the set of all real numbers.

The maximum value is 3, then the amplitude must be 3: y = 3 cos x

The y-intercept is (0,-3) then it is the functio y = 3 cos x, reflected around the x-axis: y = - 3 cos x

So if I had this problem I would multiply 21 x 34= 714 then I would divide it by 14 which would get me 51. There would be 51 blocks in each group!
