Study Notes
Graphing Polynomial Functions
- End behavior of polynomial functions can be determined by examining the leading term.
- For the function f(x) = 2x^6 - 2x^2 - 5, graph A shows the same end behavior; graph D does not.
Graphs of Polynomial Functions
- The function f(x) = x^4 + x^3 - x^2 - x corresponds to graph A.
End Behavior of Specific Polynomial
- The polynomial f(x) = 2x^3 - 26x - 24 has end behavior where, as x approaches negative infinity, y approaches negative infinity, and as x approaches positive infinity, y approaches positive infinity.
Roots and the X-Axis
- The graph of f(x) = (x + 4)^6(x + 7)^5 crosses the x-axis at the root -7.
Graph Representation
- The function f(x) = -0.08x(x² - 11x + 18) aligns with graph C.
Intercepts of Polynomial Graphs
- For the function f(x) = -x^4 + 3x^3 + 10x^2, the graph touches the x-axis at x = 0 and crosses at x = 5 and x = -2.
End Behavior Analysis
- The polynomial f(x) = 3x^6 + 30x^5 + 75x^4 exhibits end behavior where both ends go to positive infinity as x approaches both negative and positive infinity.
Function Representation
- A function f(x) that could represent the described graph is f(x) = (x - a)^2(x - b)^4.
X-Axis Intersections
- In the function f(x) = (x - 5)^3(x + 2)^2, the x-axis is touched at the root -2.
Crossing and Touching the X-Axis
- For f(x) = -4x^3 - 28x^2 - 32x + 64, the graph touches the x-axis at x = -4 and crosses at x = 1.
Graphing Functions
- The function f(x) = 0.03x²(x² - 25) corresponds to graph A.
Multiplicity of Roots
- A polynomial with roots of -5 (multiplicity 3), 1 (multiplicity 2), and 3 (multiplicity 7), with a negative leading coefficient and an even degree, behaves negatively on the interval (3, ∞).
End Behavior of Specific Polynomial
- The function f(x) = -3x^3 - x^2 + 1 has its end behavior matching that of graph D.
X-Axis Behavior
- The function f(x) = 4x^7 + 40x^6 + 100x^5 crosses the x-axis at x = 0 and touches it at x = -5.
Graph Representation for Odd Degrees
- For a polynomial with roots of -4 (multiplicity 4), -1 (multiplicity 3), and 5 (multiplicity 6), a positive leading coefficient and odd degree indicates it corresponds to graph B.
Graph Identification
- The function f(x) = 0.003x^2(x^2 - 25) aligns with graph A.
