Question 1049328: 37.The value of limit: lim(x->4)(x^2-7x+12)/(x-4) is:
a.0
b.1
c.2
d.∞ (infinity)

The function would be approximately the line y=x-3, BUT a point is MISSING for x=4. Now, you can find the value of y=x-3 for x=4.

Understand, x=4 is undefined for f(x) but is acceptable for y=x-3.

Limit as x approaches 4, of is 1.
