Plot the x-intercept of the function f(x) = (x + 4).
Click or tap the graph to plot a point.

The x-intercept is (-4,0)

Step-by-step explanation:

When you have an x-intercept, it means you have ( x , 0 ). The y-coordinate will always be 0.

Here you can replace f(x)  = y.

y = x+4

Plug in 0 for y to get 0 = x+4

Subtract 4 on both sides to single out the x.

You get x= -4

Your x-intercept would be (-4,0)

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats
