Answer:
{12,15}
Step-by-step explanation:
Given the function f(x) = x+5, if the range of the function is {7,9}, the domain of the function is derived by simply finding the value of the function at each end point.
At endpoint x = 7,
f(7) = 7+5
f(7) = 12
At endpoint x = 9
f(9) = 9+5
f(9) = 14.
The function domain is therefore at {12,14}
Answer:
C. 9
Step-by-step explanation:
y = -4x^2 + 2kx
subtitute 3:
y = -4(9)^2 + 2k(9)
y = -4(81) + 18k
let y = 0
=> 0 = -324 + 18k
=> k = 324/18 = 9
this is my calculations hope it helps
The answer is going to be 9. Hope that helped.
Percent formula : is/of = %/100
is = 48
of = 160
% = x
48/160 = x/100
cross multiply
160x = 4800
x = 4800/160
x = 30......so 48 is 30% of 160
