Answer:
The right values of y :
5 , 3 , 5
Step-by-step explanation:
Let f be the function of equation : y = 1/2x² + 3
then f(0) = 1/2(0)² + 3 = 0 + 3 = 3
f(2) = 1/2(2)² + 3 = 2 + 3 = 5
f(-2) = 1/2(-2)² + 3 = 5
Answer: 12 servings
Step-by-step explanation:
If the lunch lady makes equal servings of 1/2 pound each and she had 6 pounds total it would be written like this: 6÷1/2
but you can't divide by a fraction so you multiply by the opposite reciprocal like this 6×2/1 or just 6×2
which gives you your answer of 12
Answer:
y = x²/4 + x/2 + 21/4 ⇒ -9 ≤ x ≤ 7
Step-by-step explanation:
∵ x = 2t - 1
∴ 2t = x + 1 ⇒ t = (x + 1)/2
∵ y = t² + 5
∴ y = [(x + 1)/2]² + 5 = (x² + 2x + 1)/4 + 5
y = x²/4 + x/2 + 1/4 + 5 = x²/4 + x/2 + 21/4
∵ -4 ≤ t ≤ 4
∴ -9 ≤ x ≤ 7
