Exponential function f is represented by the table. x -2 -1 0 1 2 f(x) -46 -22 -10 -4 -1 Function g is represented by the equati
Scrat [10]

The statement that describes better about function is "Both functions are increasing, but function g increases at a faster average rate." since option (c) is correct.

Given the table

x         f(x)

-2        -46

-1         -22

0         -10

1           -4

2          -1

We have to choose which statement describes better about function

Let us assume f(x)=ab^x+c

at x=0, f(0)=-10

So, -10 =a+c

Similarly, by satisfying the above table in the f(x)

f(x)=\frac{33}{5} (\frac{1}{11})^x-\frac{17}{5}

f'(x) > 0

So we can say that f(x) is an increasing function.

g(x) = - 18  (\frac{1}{3}  )^ x + 2

g^ \prime (x) = - 18 (\frac{1}{3}  )^ x  ln(1/3)

ln(1/3) < 0

So, g^ \prime (x) > 0

So, g(x) is an increasing function.

For any x∈f(x) and  x∈g(x) g'(x) > f'(x)

So, g increases at a faster average rate

Thus, Both functions are increasing, but function g increases at a faster average rate.

Someone help me with this ples with steps
SSSSS [86.1K]

Answer:

x=\frac{21}{4}

y=\frac{21}{2}

Step-by-step explanation:

equation (1): \frac{1}{2} (2x+y)=\frac{21}{2}

equation (2): y=2x

solve the system by substitution

step1: sub (2x) for y in equation 1:

\frac{1}{2} (2x+y)=\frac{21}{2}

\frac{1}{2} (2x+2x)=\frac{21}{2}

step2: simplify the expression:

\frac{1}{2} (4x)=\frac{21}{2}

2x=\frac{21}{2}

(divide by 2 for both sides)

x=\frac{21}{4}

To find the value for y sub 21/4 for x in equation 2:

y=2x

y=2×(21/4)

y=\frac{21}{2}

Ryan went to the store to buy a CD. The CD was on sale for 10% off. If Ryan paid $13.50 for the CD, what was the original price
nydimaria [60]
<span>well first off, you take 1350/9=150
then you add it all together 1350+150=1500
then your full answer would be $15 was the original price
