Answer:
Step-by-step explanation:
exponential function :
where a = y intercept and b = factor ( what you multiply by )
looking at the table the y intercept is at (0,10) so a = 10
so we now have y = 10 * (b)^x
to find the factor we simply plug in one of the ordered pairs.
note that the ordered pair chosen does not effect the outcome
i chose (2,250)
we have y = 10 * (b)^x
(x,y) = (2,250)
250 = 10 * (b)^2
divide both sides by 10
25 = b^2
take the square root of both sides
5 = b
the final equation would be f(x) = 10 * (b)^x
Answer:
Jeffrey is correct
All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
step 1
Find the slope between -5, 6 and -3, 2
substitute the values in the formula
step 2
Find the slope between (-1, -2) and (0, -4)
substitute the values in the formula
step 3
Find the slope between (-3, 2) and (0, -4)
substitute the values in the formula
therefore
Jeffrey is correct
