Answer:

Option C [-3, ∞).

Step-by-step explanation:

In the given function f(x) = √(x+3) when drawn graphically we see that the graph has a growth starting form x=(-3).This can be evaluated by drawing a tangent on every point of the graph.

Here the graph is increasing form (-3) to ∞ which is the domain of the function.

Therefore the function is increasing over the interval of [-3, ∞).

Hence Option C is the correct answer.

On a coordinate plane, a piecewise function has 3 lines. The first line has a closed circle at (negative 3, negative 4) and cont

ICE Princess25 [194]

Answer:Answer:

f(-2) = 2

f(0) = 3

f (4) = -1

Step-by-step explanation:

The equation of the straight line passing through the points (0,3) and (-4,1) is

⇒ 2(y - 1) = x + 4

⇒ 2y - 2 = x + 4

⇒ 2y = x + 6

⇒

Again, the equation of the line passing through the points (0,1) and (4,-1) is

⇒ - 2 ( y + 1) = x - 4

⇒ - 2y = x - 2

⇒

Therefore, the function is defined as

for x ≤ 0 ........... (1) and

for x > 0 ............ (2)

Therefore, f(-2) = 2 from equation (1).

f(0) = 3 from equation (1)

And f (4) = -1 from equation (2). (Answer)

Triangle sum theorem

sleet_krkn [62]

Answer:

e= 60

Step-by-step explanation:

we know that triangles add up to 180

so 35+24+2e+1= 180

simplify: 60+2e= 180

subtract 60 on both sides: 2e= 120

divide both sides by 2: e=60

Two more than a certain number is 15 less than the product of 7/8 and the number equation

garri49 [273]

Answer:

The number is -136.

Step-by-step explanation:

Let the number be x, so we have the equation:

x + 2 = 7/8 x - 15

x - 7/8 x = -15 - 2

1/8 x = -17

x = -17 * 8 = -136.

Dillon studied 3 6/7 hours for his English test. He studied 5 3/14 hours for his math test. How much longer did he study for his

yaroslaw [1]

Answer:

$1 \frac{5}{14}$ , $\frac{19}{14}$

Step-by-step explanation:

How much longer did he study for his math test?

$E=3\frac{6}{7}$

$M=5\frac{3}{14}$

$x=difference$

An equation for this would resemble this:

$M- E=x$

Now before we get into any equation solving let's get the denominators equal to each other. we can do this by multiplying the numerator and denominator by 2. $\frac{6(2)}{7(2)}=\frac{12}{14}$

Now we can solve the equation:

$5\frac{3}{14} - 3\frac{12}{14} =\frac{19}{14}$

$1 \frac{5}{14}$ , as a mixed number
