find the limit of the function by using direct substitution. lim(x^2+3x-1) as x approaches 3.
answers:
a) 17
b) 0
c) -17
d) does not exist

Option A

Step-by-step explanation:

We have to find the limit of the function (x² + 3x - 1) as x approaches 3.

lim[f(x)] = lim (x² + 3x -1)

x⇒3         x⇒3

            = (3)² + (3 × 3) -1

            = 9 + 9 - 1

            = 18 - 1

            = 17

Option A is the answer.

50

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
