Which function has the smallest x-intercept value, if it exists? O f(x) = 3x – 9
O F(x) = +4
O f(x) = Vx+1
Of(x) = x²

The smallest x-intercept is x = -1, from equation 3.

Step-by-step explanation:

The x-intercept value of a function happens when "y", or in this case f(x), is equal to 0. Therefore we need to analyze each equation by making f(x) = 0 and finding x.

(a)

(b)

Since this is a constant function for which f(x) = 4, then there will be no x-intercept.

(c)

(d)

From these options the smallest x-intercept is x = -1.

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
