AB is horizontal. The slope of a horizontal line is zero.
Hey there!
The correct answer would be that there are no x-intercepts. When you look at the graph, the function does not appear to pass through the x axis.
Therefore, your function has no x-intercept.
Hope this helps! :)

is a classic approximation, true for small x.
The next term in the polynomial expansion will be
where k is a positive number. So our estimate 1-x is definitely an underestimate on both sides of x=0.
Since for negative xs the exponential rises exponentially and the line only linearly, the exponential exceeds the line for all negative x. For positive x, the line quickly goes negative while the exponential is always positive.
So, there's no interval for which our approximation is an overestimate.

sorry but question no 1 i cant answer cause the pic is too blurry
Answer:
y = 2x + 11
Step-by-step explanation:
The point slope formula for a line is
y - y1 = m(x - x1)
We already have the slope, 2, and we can substitute the point (-4, 3) into (x1, y1):
y - 3 = 2(x + 4)
y - 3 = 2x + 8
y = 2x + 11
