Answer is x=3 cuz x^2-7x-18=0, so you would Cancel out the -18 to make it a positive 18th then bring the positive 18 over to the zero and then add 18 to 0 obviously it’s 18 and then you figure out the X to the second power minus 7X which is just 6X because x to the 2 power is x then you subtract seven eggs from X which is 6X so than6X equals 18 and then divide 18 by 6 which is three so x=3

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
