Start with which equations are written in function notation?
The only ones are the first and last, not the “y=“ ones.

Then look at the equations.
h(x) = x^2 would be a parabola, so the range wouldn’t be all real numbers. It’d only be non-negative numbers.
g(x) = 1/2 x + 3/2 would be a line. This has a range of all real numbers.

NikAS [45]

Hey there!!

The formula for the area of a square - s²

where s = side

s² = 345

s = √345

s = 18.57 ft

Fence shall be three sides

So 18.57 × 3

The required answer = 55.71 ft

Hope my answer helps!

The equation d=3t represents the relationship between the distance (d) in inches that a snail is from a certain rock and the tim

Maksim231197 [3]

Answer:

3 minutes

Step-by-step explanation:

d=3t is our formula.

d being the distance (9 inches for this problem)

t is the time in minutes

Substituting our known information would make our equation look like:

9 = 3t

to solve for t we divide both sides of the equation by 3

9/3 = 3t/3

3 = t

So if a snail travels 3 inches per minute, it will have traveled 9 inches in 3 minutes.

Olin [163]

Answer:

Area covered by the fences will be 16.1 unit²

Step-by-step explanation:

Let the first parabola is represented by the function f(x) = 6x²

and second parabola by g(x) = x² + 9

point of intersection of the graphs will be determined when f(x) = g(x)

6x² = x² + 9

5x² = 9

x² = 1.8

x = ± 1.34

Now we will find the area between these curves drawn on the graph.

Area = $\int_{-1.34}^{1.34}[f(x)-g(x)]dx=\int_{-1.34}^{1.34}[6x^{2}-(x^{2}+9)]dx$

= $\int_{-1.34}^{1.34}(5x^{2}-9)dx$

= $[\frac{5}{3}x^{3}-9x]_{-1.34}^{1.34}$

= $[\frac{5}{3}(-1.34)^{3}-9(-1.34)-\frac{5}{3}(1.34)^{3}+9(1.34)]$

= $[-4.01+12.06-4.01+12.06]$

= 16.1 unit²
