If the value of a is negative, then the range will be (-∞, k) and if the value of the a is positive then the range will be (k, ∞).
<h3>What is a quadratic equation?</h3>
It's a polynomial with a worth of nothing.
There exist polynomials of variable power 2, 1, and 0 terms.
A quadratic condition is a condition with one explanation where the degree of the equation is 2.
Domain and range of linear and quadratic functions
Let the linear equation be y = mx + c.
Then the domain and the range of the linear function are always real.
Let the quadratic equation will be in vertex form.
y = a(x - h)² + k
Then the domain of the quadratic function will be real.
If the value of a is negative, then the range will be (-∞, k) and if the value of the a is positive then the range will be (k, ∞).

Answer:
⇒y=32x+18
Step-by-step explanation:
You write it as 0.5. Just divide both numbers
Answer:
B. 3 square feet
Step-by-step explanation:
The formula for surface area is:
2lw+2lh+2wh
Box F's surface area is just plugging in those variables
2(3)(3)+2(3)(3)+2(3)(3)=54
Box J's surface area is the same way
2(2)(4.5)+2(2)(3)+2(4.5)(3)=57
The difference is 57-54=3
The answer is B. 3 square ft
Answer:
26.8cm²
Step-by-step explanation:
the area if a rectangle is 53.6cm^2.If the length is multiplied by four and the width is halved, the area would then be?
Area of rectangle = length x width
53.6 = 4L x 1/2 W
53.6 = 2L × W
Divide both sides by 2
L × W = 53.6 ÷ 2
New area = 26.8cm²
