Sandra graphed the system of equations that can
be used to solve
What are the roots of the polynomial equation? -
Answer -3, 4
Using the quadratic formula to solve 2x2 = 4x - 7,
what are the values of x? - Answer C
look at photo
A toy rocket is launched straight up into the air
with an initial velocity of 60 ft/s from a table 3 ft
above the ground. If acceleration due to gravity is -
16 ft/s2, approximately how many seconds after
the launch will the toy rocket reach the ground?
h(t) = at2 + vt + h0 - Answer 3.80 s
Which equation represents a linear function? -
Answer y - 2 = -5(x - 2)
According to the Fundamental Theorem of Algebra,
how many roots exist for the polynomial function?
, f(x) = (x3 - 3x + 1)2 - Answer 6 roots
Which expression is equivalent to ? - Answer A
look at photo
The graph of f(x) = 4x3 - 13x2 + 9x + 2 is shown
below.
On a coordinate plane, a function is shown. The
function starts from the bottom of quadrant 3 and
goes up through the x-axis at (0, negative 0.25)
and then through the y-axis at (0, 2). It then starts
to curve down at (0.5, 4) until it reaches (1.75,
negative 0.5). It then curves up and crosses the x-
axis at (2, 0) and goes up approaching x = 3.
How many roots of f(x) are rational numbers? -
Answer 3
What are the solutions of the equation 9x4 - 2x2 - 7
= 0? Use u substitution to solve. - Answer C
Which phrase best describes the translation from
the graph y = 2x2 to the graph of y = 2x2 + 5? -
Answer 5 units up
