A classmate said that the vertex of g(x) = -5(x + 2)^2 - 4 is (2, 4). Is your classmate correct? If not, what is the correct ver tex?
1 answer:
Answer: Classmate is wrong. Vertex = (-2, -4)
Step-by-step explanation:
The vertex form of a quadratic equation is: y = a(x - h)² + k where
"a" is the vertical stretch -a is a reflection over the x-axis h is the horizontal shift (positive = right, negative = left) k is the vertical shift (positive = up, negative = down)
Given: g(x) = -5(x + 2)² - 4
↓ ↓
h= -2 k= -4
Vertex = (-2, -4)

money he gets daily - 160
total days in September month - 30
his monthly income - 160×30 = 4800
hence the money he gets in month of September is 4800 (units)
12 inches = 1 foot.
144 inches = 1 square foot.
To find 4 square feet, you need to multiply by 4.
144 * 4 = 576
576 inches = 4 square feet

Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ]
2-10/0-(-4)
-8/4
-2
The error is that he/she subtracted the values of each point instead of subtracting the y values together and x values together in reverse order as shown in the formula above.
