Question

Find the limit of the function by using direct substitution. limit as x approaches zero of quantity x squared minus five.

Answer 1

Answer:

The value of limit is -5

Step-by-step explanation:

Given: $\lim_{x\rightarrow 0}x^2-5$

We need to find limit by direct substitution.

"quantity x squared minus five" : x²-5

We will put x=0 into function.

$L=\lim_{x\rightarrow 0}x^2-5$

$L=0^2-5$

$L=0-5$

$L=-5$

Hence, The value of limit is -5

Answer 2

Simply plug in x = 0

f(x) = x^2 - 5
f(0) = 0^2 - 5
f(0) = -5

Answer: -5
