In the given figure there are 3 graphs
The line represents a linear function
The parabola represents a quadratic function
The third graph which approaches to the negative part o the x-xis is the exponential function
The x-intercept of the line is (-2, 0)
x-intercept means intersect the x-axis at point (-2, 0)
There is only one graph that intersects the x-axis at (-2, 0)
It is the line, the linear function h(x)
The range is between 0 to infinity (0, ∞)
The range is the values of y
There is only one graph that has all values of y over the x-xis
it is f(x) the exponential function
From the problem :
In multiplying expressions with the same bases, the exponent will be added accordingly.
For example :
the exponent of a are m and n, and the product will be a raised to the sum of m and n.
Applying this to the problem, we have :
The answer is d. 6^-1
