The limit of the given function f(x) = 5[tex]x^{4}[/tex] – x2 + 6x – 1 approach negative 1 will be -3 so correct option will be (A).
What is limit?
Limit, a nearness in mathematical notion, is largely used to give values to some functions at locations that were usually not given or defined, in a manner consistent with neighboring values.
In another word, limit is a mathematical concept in which we find out the value of any function at a point by its adjacent very close point.
Because the value of that function at that point doesn't define.
For example, limits tend to 0 of sine x, limits tend to infinite of cosx.
Given that the function
5[tex]x^{4}[/tex] – x2 + 6x – 1
Limit is from x is tends to -1
[tex]\lim_{x \to \-1} f(x)[/tex] = 5(-1)⁴ - (-1)² +6(-1) -1
⇒ -3 hence it will be the correct answer.
