- 4

Step-by-step explanation:

The average rate of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 2, 2 ]

f(b) = f(2) = 9 ← from table value of f(x) for x = 2

f(a) = f(- 2) = 25 ← from table value of f(x) for x = - 2, thus

average rate of change = = = - 4

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
