Answer: the no. is doubled every time we get an answer. therefore the next two no.s n the sequence are 48, 96
y + 7 =
(x + 4)
the equation of a line in ' point- slope form ' is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m =
and (a , b ) =( - 4, - 7)
y + 7 =
(x + 4) → equation in point- slope form
Answer:
y = 3^(1 + x)
Step-by-step explanation:
Notice that each time x increases by 1, y increases by a factor of 3.
Thus, the required equation has the form y = 3^x.
Check: If x = 0, do we get 3? No. Therefore we must modify the exponent:
y = 3^(1 + x)
Check: If x = 0, do we get 3? 3^(1 + 0) = 3 (correct)
If x = 2, do we get 27? 3(1 + 2) = 3^3 + 27 (correct)
