# 1) The graph of a function f is given. (a) State the value of f(-1) (b) For what values of z is (x) 2? (c) State the domain and range of f. (d) On what interval is f increasing? (e) On what interval is f decreasing? 5-8) Determine whether the curve is the graph of a function. # 21) If r(z)-3c2-2+ 2 find f(2), f(-2)./(0), f(a + 1 ), 2/(a), fCa), f(?), and U(a)12 # 23) Find the difference quotient h-10) for the function f(z)-4 +3z-H # 27, 3031) Find the domain of these functions # 33.41) Find the domain and sketch the graph of these functions: f(a)-5 #66-68) Determine whether f is even, odd, or neither. # 64) A function / has domain I-55) and portion of its graph is shown here. (a) complete the graph of f if it is known that f is even. (a) complete the graph of f if it is known that f is odd y

Explanation / Answer

1)

a) from the graph we can see that at x=-1 y=-2

so f(-1)=-2

b) f(x) =2 that means y=2

from the graph at x=1 y=2

so x=1

c) domain = -3 to +3 ( x values)

Range = -2 to +3 ( y values)

d) function is increasing from x=-1 to x=3

e) function is decreasing x=-3 to x=-1
