An exponential function is a function in which the independent variable is an exponent. Exponential functions have the general form y = f (x) = ax, where a > 0, a≠1, and x is any real number. The reason a > 0 is that if it is negative, the function is undefined for -1 < x < 1.

Attempted but just couldnt understand (25Points)

Answer:

a) Function:Yes

b) Domain: $-5\:$

c) Range: $-5\le y\le 3$

Step-by-step explanation:

The given graph passes vertical line test hence it is a function

The given function has x-intercepts at $x=-4.5, x=-1,x=3.5$

We can therefore write this function in factored form as $y=a(2x+9)(x+1)(2x-7)$

There is a y-intercept at (0,-2)

$-2=a(2*0+9)(0+1)(2*0-7)$

$-2=-63a$

$a=\frac{2}{63}$

The required function is

$y=\frac{2}{63}(2x+9)(x+1)(2x-7)$

b) The domain refers to all values of x for which this function is defined.

The domain from the graph is $-5\:$ because there are holes at the end of the graph.

c) The range is the value of y for which x is defined or the graph exists.

From the graph the range is $-5\le y\le 3$

Foram prescritos 500mg de dipirona para uma criança com febre.Na unidade tem disponivel ampola de 1g/2ml.Quantos g vão ser admin

Valentin [98]

De acordo com a disponibilidade da unidade, há apenas a seguinte dosagem: 1g/2mL - ou seja, uma grama de dipirona a cada 2mL

O enunciado está meio mal formulado, pois é dito que foram prescritos 500mg de dipirona e é essa quantidade de farmaco que a criança tem que tomar. Deseja-se saber quantos mL deverao ser administrados.

Fazendo a classica regra de 3, podemos chegar no volume desejado:

(atentar que 500mg = 0,5g)

g mL

1 --------- 2

0,5 --------- X

1 . X = 0,5 . 2
