Answer:

The domain will be all real numbers, range will be all real numbers below -3

Step-by-step explanation:

its quadratic so it goes forever left and right. but the vertex has a y value of -3. It is a negative sloped graph, so anything below that is in the range

Solve 4 square root of 3 = 8cos

sukhopar [10]

Therefore $\theta = 30^\circ$

Step-by-step explanation:

Given,

$4\sqrt{3 } =8 cos \theta$

$\Leftrightarrow cos \theta =\frac{4\sqrt{3} }{8}$

$\Leftrightarrow cos \theta =\frac{\sqrt{3} }{2}$

$\Leftrightarrow cos \theta =cos 30^\circ$

$\Leftrightarrow \theta = 30^\circ$

Therefore $\theta = 30^\circ$

Y=f(×)=9× Find f(×) when x =1/2

mojhsa [17]

<h3>f(x) is equal to 4.5 when x = 1/2</h3>

Solution:

Given that,

$y = f(x) = 9x$

We have to find f(x) when x = 1/2

We can solve by substituting x = 1/2 in given function

$f(x) = 9x\\\\Plug\ in\ x = \frac{1}{2}\\\\f(\frac{1}{2}) = 9 \times \frac{1}{2}\\\\f(\frac{1}{2}) = 4.5$

Thus f(x) is equal to 4.5 when x = 1/2

Help pls solve the equation 4 to the power of 3x ÷ 2 to the power of 4x =32

777dan777 [17]

Answer:

x = 5/2

Step-by-step explanation:

(4^3x)/(2^4x) = 32

(2^6x)/(2^4x) = 32

2^2x = 32

2^2x = 2^5

2x = 5

x = 5/2
