Happy New Year from MrBillDoesMath!
Answer:
y = -7
Discussion:
A somewhat obscure question. By f containing the point (1,y) I think they mean f(1) = y. As
f(x) = 2^x - 9 =>
f(1) = 2^ (1) - 9 = 2 - 9 = -7 = y
so y = -7
Thank you,
MrB
f(x) = -7
Step-by-step explanation: Subsitute 1 to get your y point
f(x) = 2^x - 9
f(x) = 2^1 - 9
f(x) = 2 - 9
So, the y point is -7. As an ordered pair, it is (1, -7)
Hope this helps you!!! :)
