If the parabola line crosses the x-axis twice, then it has two solutions, or the maximum/minimum of it is a point on the x-axis that means it has two solutions as a double root.
Answer:
224
Step-by-step explanation:
Hello!
To find f(-7) you simply plug the value, -7, into the function.
This will get you:
f(-7) = 4(-7)^2 - 4(-7)
Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!
This will get you:
f(-7) = 4(49) - 4(-7)
f(-7) = 196 - (-28)
f(-7) = 224
Hope this helps!
Answer:b is the answer
Step-by-step explanation:
(3/4, -1/8)
The slashes represent fractions "/"
1 ft = 12 inches....so 4 ft = (4 * 12) = 48 inches
ratio is : 48 to 15...or 48/15 or 48:15......which reduces to 16/5 in lowest terms
