Determine which is the graph of the given function.

a

Step-by-step explanation:

step 1:

for x is less than -5 the f(x) = -3

step 2:

for x is greater than or equal to -5 and less than or equal to 15, f(x)=x+2 and since x contains the value of 15 the Value of x=15 results in f(x)=x+2 15+2=17.

step 3

for x is greater than 15, f(x)= -x+2.

only exists in the graph a.

13.46

step-by-step explanation:

16.80 x .20 = 13.46

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
