Match the following key attributes for the graph

anzhelika [568]

Answer:

Domain: [-4, ∞]

Range: [-6, ∞]

Step-by-step explanation:

The domain is the set of the possible x values

The range is the set of the possible y values.

In the graph, we can see that the function cuts in a given part. We can see that for the x-values, the smallest one is x = -4, and then the function extends to the right (we see no limit at the right, then there is none)

This means that the domain is:

D: [-4, ∞]

For the y-values, the smallest value is when x = -4, and the y-value is -6

Then we can see that, as x increases, the same happens for y.

Then the range is:

R: [-6, ∞]

Differentiate 4^xlnx

Vsevolod [243]

If you mean

$\dfrac{\mathrm d}{\mathrm dx}\left[4^x\ln(x)\right]$

then first write $4^x=e^{\ln(4^x)}=e^{\ln(4)x}$ . Then by the product rule,

$\dfrac{\mathrm d}{\mathrm dx}\left[4^x\ln(x)\right] = \ln(4)e^{\ln(4)x}\ln(x) + \dfrac{e^{\ln(4)x}}x = \ln(4)4^x\ln(x)+\dfrac{4^x}x=\dfrac{4^x}x\left(\ln(4)x\ln(x)+1\right)$

If you instead mean

$\dfrac{\mathrm d}{\mathrm dx}\left[4^{x\ln(x)}\right]$

you can again rewrite $4^{x\ln(x)} = e^{\ln\left(4^{x\ln(x)}\right)}=e^{x\ln(x)\ln(4)}$ . Then by the chain and product rules,

$\dfrac{\mathrm d}{\mathrm dx}\left[4^{x\ln(x)}\right] = e^{x\ln(x)\ln(4)}\ln(4)\left(\ln(x)+1\right) = 4^{x\ln(x)}\ln(4)(\ln(x)+1)$

The low temperatures for one week at a ski resort were: -24, -15, -21, -32, -18, -9, & -14. What was the mean low temperatur

monitta

Add the temps up
-24 + (-15) + (-21) + (-32) + (-18) + (-9) + (-14) = -133
now divide by how many numbers there are
-133/7 = -19 <== the mean (average)
