Answer:
f(x) = 16x2 + 32x - 9
To find the "zeros", set f(x) = 0:
0 = 16x2 + 32x - 9
The equation is solvable by factoring or by using the quadratic formula. The factors (use the "ac" method) are:
0 = (4x-1)(4x+9)
x = 1/4 = 0.25 and x = -9/4 = -2.25
Step-by-step explanation:
Answer:
-1/2
if it's not right let me know
Step-by-step explanation:
Inverse Property, I am pretty sure. Not sure though.
3 < x < 13
This is because the sum of two sides must be greater than the length of the third side.
