Check all the statements that are true:

a. the exponential function is the fastest growing of all functions, i. e. every function f is big-o of ex.
b. if f is of order g, so is 10f.
c. if f and g are both of order h, then their sum is of order h as well.
d. if f and g are both big-o of h, then so is their sum.
e. if f and g are both big-o of h, then so is their product.
f. if p and q are polynomials, then p is big-o of q exactly if the degree of p is less than or equal the degree of q.

answer: need picture of problem

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
