Answer:
The third graph is the graph of the given function
Step-by-step explanation:
A simple technique that can be used to identify the graph that matches the given function is; determination of the x and y-intercepts. In this case, determining the y-intercept and then using elimination will suffice in matching the function with its graph. At the y-intercept the value of x is always zero, so we replace x with zero in the right hand side of the equation; y(x) = 2^(0+3) = 8. The graph of the function should therefore cross the y-axis at the point (0,8). The third graph is the graph of the given function.
The cities are 14.7 inches apart on the map.
An inch on the map is 10 miles on the ground. That is what a scale of 1 in : 10 miles means.
If a distance is 147 miles on the ground therefore, on the map it will be:
= Distance on map / conversion factor
= 147 / 10
= 14.7 inches
The distance between the two cities on the map is 14.7 inches.
