Question

Graph time...........

Answer 1

The answer is graph 3

Explanation:

In the given set of graphs

Graph number 3 shows the graph of the given exponential function.

In the given graph we can see that the vertical intercepts are (0,8).

So the graph will touch y axis on 8 and x axis on -7 after which it will become linear on -x axis.

Answer 2

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.
