Question: We are solving: limx 2 ( 4 x + 5 ) lim _ { x to - 2 } ( 4 x +

We are solving:
limx2(4x+5)\lim_{x \to -2}(4x +5)x2lim(4x+5)
Explanation:
Direct Substitution: Since the function f(x)=4x+5f(x)=4x +5f(x)=4x+5 is a linear function (and continuous everywhere), we can directly substitute x=2x =-2x=2 into the function.
Substituting x=2x =-2x=2:
f(2)=4(2)+5f(-2)=4(-2)+5
