Chapter 1 Self Test
Click
for True and
for False. Use a calculator when necessary.
1) Evaluate f(2) if f(x) = -x2+4x +1
2) The domain of f(x) = (x2 - 9x + 19) is (-inf,inf)
3) The domain of y = | x - 2 | is [2, inf)
4) The range of of y = | x - 2 | is [2, inf).
5) The function y = x3 is always increasing.
6) The function y = 5x2- 7x + 16 = 0 has a maximum.
7) The point (2, 1) is on the line 4x - 2y =6
8) 3 is not in the domain of y = 1/(x2- 9 )
9) If g(t) = | t - 5| , then g(x) = x - 5
10) y = x3+ 6 has a vertical shift of 6 units compared to
y =
x3.
11) If f(x) = x+3 and g(x) = 2x, then f(g(5)) = 13
12) The equation of the line passing through the points (-2,5) and (4, -7 )
