Question
Identify where any horizontal tangents exist for the function.
![The function depicted in the image is a polynomial function of degree three. It is expressed as:
\[ f(x) = x^3 + 7x^2 - 8 \]
This function represents a cubic polynomial where:
- The variable \( x \) is raised to the power of three, denoting the cubic term (\( x^3 \)).
- There is also a quadratic term represented by \( 7x^2 \).
- A constant term of \(-8\) is included.
In terms of graphing, a cubic function typically exhibits an "S" shaped curve, which may have one or two inflection points, depending on the roots and turning points of the specific polynomial. The leading coefficient \( 1 \) (from \( x^3 \)) indicates that the end behavior of the graph will rise to positive infinity on the right and descend to negative infinity on the left.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F784ad4b4-6318-4d02-a8d3-2c6783ec95ff%2Fbed992a0-7e37-478e-9d6f-5d7a9ab106b6%2F7e86vxf_processed.png&w=3840&q=75)
