Answer:

The third graph is the graph of the function provided

Step-by-step explanation:

A simple technique that can be used to identify the graph that matches the given function is; determination of the y-intercept and then using elimination method to match the function with its graph. At the y-intercept the value of x is always zero, so we replace x with zero in the right hand side of the equation; y(x) = 2^(0+3) = 8. The graph of the function should therefore cross the y-axis at the point (0,8). Thus, the third graph is the graph of the given function.

Answer:

Option C is correct.

Step-by-step explanation:

An exponential is in the form of :

f(x) = ab^x

where

a is the initial value and

b is the growth factor.

If b> 1 , then the graph is increasing.

if 0<b<1, then the graph is decreasing.

Given the function:

f(x) = 2^{x+3}

we can write this as:

f(x) = 2^x \cdot 2^3 = 8 \cdot 2^x

⇒f(x) =8 \cdot (2)^x

Here, b = 2 > 1

y-intercept: The graph crosses the y-axis

Substitute x = 0 and solve for f(x):

f(0) =8 \cdot (2)^0

⇒f(0) = 8

⇒a = 8

Graph of this function:

We make table for some values of x;

x               f(x)

-1               4

0                8

1                 16

2                32

Note as x increase, f(x) increases

Now, plot these points on the coordinate plane.

You can see the graph of the given function shown below.

Write an equivalent expression for 25x - 45 using the properties of operations. Hint: find the GCF of 25 and 45. You use parenth
Oksana_A [137]

Answer:

25x - 45 = 5(5x - 9)

Step-by-step explanation:

Find the greatest common factor (GCF) of 25 and 45.

You can do this several ways, but one way is to list all the factors of both numbers and find the greatest common one:

Factors of 25: 1, 5, 25

Factors of 45: 1, 3, 5, 9, 15, 45

Therefore, 25 and 45 have 2 common factors: 1 and 5

So the greatest common factors is 5

25x - 45 = 5(ax - b)

To find the value of a, simply divide 25 by 5: 25 ÷ 5 = 5

To find the value of b, divide 45 by 5: 45 ÷ 5 = 9

25x - 45 = 5(5x - 9)

Simplify the rational expression by rationalizing the denominator √15/√6x
noname [10]

Answer:

√10/2x

Step-by-step explanation:

Multiply by √6 on the top and bottom to rationalize the denominator.

(√15×√6)/(√6x×√6) = √90/6x = (√9×√10)/6x = 3√10/6x = √10/2x
