A: given f(x) = x^2 + 16 - 24 and g(x) = x^2 - 5x - 17, find (f+g)(x), then find (f+g)(3)

(possible answers for (f+g)(3): 2x^2 + 11x - 41 or 2x^2 + 11x - 7)

b: given f(x) = 4x^3 - x^2 - 68x + 35 and g(x) = x^3 + 4x - 11, find (f - g)(x), then find (f - )

(possible answers for (f-): 3x^3 - x^2 - 72x + 46 or 3x^3 - x^2 -64x +24)

show work if possible for you : )

Step-by-step explanation:

A. Knowing that the functions are:

You need to add them in order to find . Then, you get:

To find:

Substitute into and evaluate.

Then, this is:

B. The functions f(x) and g(x) are:

You need to subtract them in order to find :

To find:

Substitute into and evaluate.

Then, this is:

y = x + 95

y = 42 + 95

y=137 mm hg

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
