With the recent technologies and scientific innovations we have now on studying and providing detailed analyses of the polar ice cores, it is roughly estimated that we could profile the ancient climate the Earth had in a time period as early as 800,000 years in order to explain the most recent climate change.

Determine the zeros
The best way to solve this is to apply the graphical method.
First, we plot the graph of: 
<em>See attachment </em>
Next, we write out all values of x when the line crosses the y-axis.
From the attached graph, the points are (approximately):


Option (d) is the closest to the above values.
<em>Hence, the zeros are: -1.4 and 3.4</em>

What value cause a stretch
For the function to stretch, then the scale factor must be greater than 1.
From the list of options.
Only 1.5 is greater than 1 i.e. 1.5 > 11.5>1
Hence, 1.5 will cause a stretch.
