Cubic binomial. There is one variable of 2 that is raised to the cubic power.
2x^2 - 7
we can plug any values of x into this The domain is All Real x.
The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7
so the range is f(x) <= -7 or (-∞, -7]
a) x-intercepts (where it passes through the x-axis) are: 0.05, 0.745, 0.8, 1.45, 1.55, 2.2
The x-intercepts represent when height = 0 and y-intercepts represent when time = 0
b) The graph is positive when height is positive: [0.05, 0.745] U [0.8, 1.45] U [1.55, 2.2]
c) The graph is negative when height is negative: [0, 0.05] U [0.745, 0.8] U [1.45, 1.55] U [2.2, ∞)
d) The average rate of change is the slope (rise/run) between the coordinates when x = 0.75 <em>(y = -5)</em> and when x = 1.125 <em> (y = 1.7). </em>
slope = = = 6
Answer:
The digits that can replace are 5 and 4
Step-by-step explanation:
Let
x -----> the digit
we have
3,408 < 3,X30 < 3,540
Divide into two inequality
<em>Solve for the first inequality</em>
1) 3,X30 < 3,540
The digits that can replace X are -----> 5,4,3,2,1,0
<em>Solve for the second inequality</em>
2) 3,408 < 3,X30
The digits that can replace X are -----> 9,8,7,6,5,4
The solution are all values of X common in both inequalities
therefore
The digits that can replace are 5 and 4
