Hi there,

Please I need help in solving this questions.

(1) Jason leaves Detroit at4:00PM and drives at a constant speed west along I-94. He passes Ann Arbor, 40 mi from Detroit, at4:50PM.(a) Express the distancedtraveled in terms of the timet(in hours) elapsed.

d(t) =

(2) Evaluatef(6), f(0), and f(7) for the piecewise defined function.

f(x) =x+4ifx< 0

2xifx0

f(6)=

f(0)=

f(7)=

What is the slope of this line?

(3) Find each of the following functions and state their domains. (Enter the domains in interval notation.)

f(x) =x³+2x²,g(x) =5x²2

(a)f+g

f+g=

domain=

(b)fg

fg=

domain=

(c)fg

fg=

domain=

(d)f/g

f/g=

domain=

(4) Find the functions and their domains. (Enter the domains in interval notation.)

f(x) =4x+5, g(x) =x²+x

(a)fg

(fg)(x)=

domain

(b)gf

(gf)(x)=

domain

(c)ff

(ff)(x)=

domain

(d)gg

(gg)(x)=

domain

Thank you
