How do you find the limit of #(x^2+1)^3 (x+3)^5# as x approaches -1?

Answer 1

256

Since neither of the functions are undefined or indeterminate for x = -1 then the limit may be evaluated by #color(blue)"substitution"#
#rArrlim_(xto-1)(x^2+1)^3(x+3)^5#
#=lim_(xto-1)(x^2+1)^3xxlim_(xto-1)(x+3)^5#
#=2^3xx2^5=2^8=256#

Answer 2

To find the limit of (x^2+1)^3 (x+3)^5 as x approaches -1, we can substitute -1 into the expression and evaluate it. Plugging in -1 for x, we get (-1^2+1)^3 (-1+3)^5, which simplifies to (0)^3 (2)^5. Since any number raised to the power of 0 is equal to 1, we have 1 * 2^5, which equals 32. Therefore, the limit of (x^2+1)^3 (x+3)^5 as x approaches -1 is 32.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
