Press
for
True and
for False.
1.
The correct graph of y = 2(x-3)2 -1 is Graph
b.
2)
This is the graph of y = -(x + 1)2 + 3 written in standard form.
3. The x and y-intercepts: y = x2 - 5x + 4 are (0, -4), (0, 1), (-4, 0).
4) The maximum point on the graph of f(x) = -x2- 2x + 2 is ( -1,3). ( Use a grapher )
5) Use a graphing utility to estimate the range of f(x) = x2+ 10x + 21.
The range is [4, inf).
![]()
![]()
6)All the real zeros of the polynomial function:
f(x) = x3 - 3x2- 4x are x = -4, and 1
7)
The correct graph of f(x)= x3 - 1/2 is Graph a.
8) Divide: (x3 + 8) ÷ (x + 2).
The quotient is x2 - 2x + 4.
![]()
![]()
9) Find all of the real solutions: x3 - 7x + 6 = 0.
x = -2, -1, 3
![]()
