Answer:

$\bold{y+1=5(x+1)}$

Step-by-step explanation:

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\(-1,\,-1)\ \implies\ x_1=-1\,,\ y_1=-1\\(0,\,4)\ \implies\ x_2=0\,,\ y_2=4\\\\m=\dfrac{4-(-1)}{0-(-1)}=\dfrac{5}{1}=5$

$y-y_1=m(x-x_1)$ - point-slope form of Equation of the Line

$x_1=-1\,,\ y_1=-1\,,\ m=5\\\\equation:\\{}\qquad\qquad y-(-1)=5\big(x-(-1)\big)\\\\{}\qquad\qquad y+1=5\big(x+1\big)$

Which function has a range of y < 3?<br> y - 3(2)<br> y = 2(3)<br> O y=-(2)x+ 3<br> Oy- (2) * - 3

defon

Given:

The range of a function is $y$ .

To find:

The function for the given range from the given options.

Solution:

In option A, the given function is:

$y=3(2)^x$

Here, $(2)^x$ is always greater than 0. So, $3(2)^x$ is also greater than 0, i.e., $y>0$ .

In option B, the given function is:

$y=2(3)^x$

Here, $(3)^x$ is always greater than 0. So, $2(3)^x$ is also greater than 0, i.e., $y>0$ .

In option C, the given function is:

$y=-(2)^x+3$

Here,

$(2)^x>0$

$-(2)^x$

$-(2)^x+3$

$y$

The range of this function is $y$ . So, option C is correct.

In option D, the given function is:

$y=(2)^x-3$

Here,

$(2)^x>0$

$(2)^x-3$

$y$

The range of this function is $y$

Therefore, the correct option is only C.
