Answer:
Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be
And , because the y-intercept is at (0, R).
So, the equation of this line would be
Where we multiply the equation by
Therefore, the equation that represents this line is
Answer:
y-intercept: (0,-3)
Step-by-step explanation:
Answer:
y = (5/4)2^x
Step-by-step explanation:
The function value increases by a factor of 40/10 = 4 when x increases by 2. The function can be written as ...
y = (reference value)·(growth factor)^((x -reference)/(change in x for growth factor))
y = 10·4^((x-3)/2) . . . . . . using point (3, 10) as a reference
This can be simplified to ...
y = 10·2^(x -3) = 10/8·2^x
y = (5/4)2^x
