Answer:
A.0
Step-by-step explanation:
y=4x²- 9x + 9
The function will intersect the x-axis when y = 0.
4x² - 9x + 9 = 0
a=4, b= -9, c=9
D=b² - 4ac = (-9)²- 4*4*9=81 - 144= - 63
D= -63, D<0, so the equation
4x² - 9x + 9 = 0 does not have real roots. That means that function y=4x²- 9x + 9 does not intersect x- axis. So, answer is A. 0.
6:45AM
7:45 minus 15 is 7:30
7:30 minus 46 mins is 6:45
So, therefore 6:45AM :)
Answer:
Domain = -3, 2, -8
Range = 1, 6, -6
Function? No
Step-by-step explanation:
Domain = x-values(no repeats)
Domain = -3, 2, -8
Range = y-values(no repeats)
Range = 1, 6, -6
Function?
No, the domain is repeating. Range can repeat but domain cannot
