Identify intervals on which the function is increasing, decreasing, or constant. g(x) = 1 - (x - 7)^2
tiny-mole [99]
<span>The derivative here is easy enough to find, first expand the equation into:
</span><span> g(x) = 3 - (x^2 - 10x + 25) = -x^2 + 10x - 22

Take the derivative: g'(x) = -2x +10

</span><span> Now, we have to find when the equation equals zero. So, we set g'(x) = 0. 0 = -2x + 10, 2x = 10, x = 5. When x is 5, this derivative will be zero, and that is the one and only time when the function is constant. When x is less than 5, you can plug in and see that the derivative will be positive, so the function is increasing when x is less than 5. When x is greater than 5, you can plug in and see that the derivative will be negative, so the function decreasing at x is greater than 5.  Hope  this helped :) have a good day!!!!!!!!!!!!!!!!!!!!!!!! </span>

From the table below, determine whether the data shows an exponential function. Explain why or why not.
nydimaria [60]

Answer:

Option a. No; the domain values are at regular intervals and the range values have a common sum 1.

Step-by-step explanation:

x1=3, x2=1, x3=-1, x4=-3

y1=1, y2=2, y3=3, y4=4


x1-x2=3-1→x1-x2=2

y2-y1=2-1→y2-y1=1


x2-x3=1-(-1)=1+1→x2-x3=2

y3-y2=3-2→y3-y2=1


x3-x4=-1-(-3)=-1+3→x3-x4=2

y4-y3=4-3→y4-y3=1


The data doesn't show an exponential function, because the domain values are at regular intervals and the range values have a common sum 1.

Solve the equation no calculator 1/5 (x +2)= 1/4 (x + 6)
NeTakaya

First, you need to get rid of the fraction by multiplying both sides by 20 and you would get:

4(x + 2) = 5(x + 6)

Now, you need to get rid of the parenthesis by distributing:

4x + 8 = 5x + 30

Subtract both sides by 5x:

-x + 8 = 30

Subtract both sides by 8:

-x = 22

Now, divide both sides by -1:

x = -22



P.S.: You don't really need a calculator to solve.

Y=-3x+6 y=9 Can anyone please help me with this i need it ASAP
Arte-miy333 [17]

Answer:

x = -1

Step-by-step explanation:

y=-3x+6

Put y as 9 and solve for x.

9 = -3x + 6

Add 3x and -9 on both sides.

3x = 6 - 9

Subtract.

3x = -3

Divide 3 into both sides.

x = -3/3

x = -1
