Question

Find the limit of the function by using direct substitution. (2 points) limit as x approaches two of quantity x squared plus eight x minus two. 18 Does not exist 0 -18

Answer 1

18

Explanation:

Given f(x) = x^2 +8x - 2

applying limit as x approaches two

`\lim_(x \to \2) _2 (x^2+8x-2)`

substitute direct method put x =2

`\lim_(x \to \2) _2 (x^2+8x-2) = 2^(2) +8(2)-2 =18`
