Answer:

y = 7 3^{x}

Step-by-step explanation:

Use the given ordered pairs to find a and b

Using (0, 7 ), then

7 = a b^{0} ( b^{0} = 1 ), thus

a = 7

y = 7 b^{x}

Using (5, 1701 )

1701 = 7 b^{5} ( divide both sides by 7 )

243 = b^{5} ( take the fifth root of both sides )

b = \sqrt[5]{243} = 3 , thus

y = 7 3^{x}

What is the solution set for x2+25=0
Masja [62]

Step-by-step explanation:

{x}^{2}  + 25 = 0 \\  \therefore {x}^{2}  =  - 25 \\ \therefore {x}  =  \sqrt{ - 25}  \\  \therefore {x}  =   \pm\sqrt{ - 1 \times 25}  \\ \therefore {x}  = \pm  \sqrt{  25}  \times  \sqrt{ - 1}  \\ \therefore {x}  =  \pm5 \: i  \\ \therefore {x}  = \{ - 5i, \:  \: 5i \} \: \\  is \: the \: solution \: set.

Help please! factoring polynomials
alexgriva [62]

Answer:

B

Step-by-step explanation:

you can use foil and the graph,

because you can see (in the graph) that the lines intersect at 1 and 4.

just use foil to help figure out which matches the slope.

something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be

-2 and -2,  2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.

Let f(x) be an exponential functionWhich transformations to the graph of f(x) would describe e - f(x - 3) ?
gayaneshka [121]

Look at the graph below carefully

Observe the results of shifting ={2}^{x}f(x)=2​x

​​  vertically:

The domain, (−∞,∞) remains unchanged.

When the function is shifted up 3 units to ={2}^{x}+3g(x)=2​x +3:

The y-intercept shifts up 3 units to (0,4).

The asymptote shifts up 3 units to y=3y=3.

The range becomes (3,∞).

When the function is shifted down 3 units to ={2}^{x}-3h(x)=2 ​x​​ −3:

The y-intercept shifts down 3 units to (0,−2).

The asymptote also shifts down 3 units to y=-3y=−3.

The range becomes (−3,∞).
