Find the derivative of the function using the definition of derivative. g(t) = 7 t g'(t) = State the domain of the function. (En

Vedmedyk [2.9K]

Answer:

$R = \{ \forall x \in \mathbf{R}|-\infty < x < \infty\}$

Step-by-step explanation:

The definition of derivative states that:

$g'(t) = \lim_{h \to 0} \frac{g(t+h)-g(t)}{h}$

Then:

$g'(t) = \lim_{n \to \infty} \frac{7\cdot (t+h)-7\cdot t}{h}$

$g'(t) = \lim_{h \to 0} 7$

$g'(t) = 7$

A constant function is a zero-order polynomial. The domain of any real polynomial is $\mathbf{R}$ . Then, the domain of the function is:

$R = \{ \forall x \in \mathbf{R}|-\infty < x < \infty\}$

Suppose it takes 2 1/2 h to drive from your house to the lake at 48 mi/h. How long will your return trip take at 40 mi/h?

Y_Kistochka [10]

Answer

The distance from the house to the lake is (2.5 hr)*(48 mi/hr) = 120 miles. The rerurn trip would take (120 mi)/(40 mi/hr) = 3 hours. Distance equals rate times time, so the distance to the lake is 2 1/2 hours times 48 miles per hour.

I hope this helps

Find f¹(x) for the function<br> f(x) = -4.<br> 2<br> f¹(x) = [?]x + [ ]

g100num [7]

Answer:

${f}^{ - 1}(x) = 2x + 8$

Step-by-step explanation:

$f(x) = \frac{x}{2} - 4 \\ \\ y = \frac{x}{2} - 4 \\ \\ y = \frac{x - 8}{2} \\ \\ x = 2y + 8 \\ \\ {f}^{ - 1} (x) = 2x + 8$

On a number line, what is x-4<-3?

goblinko [34]

Add 4 to both sides

x - 4 < -3

x-4+4 < -3+4

x < 1

To graph this on a number line, plot an open circle at 1 on the number line. Do not fill in the open circle. Shade to the left of the open circle. The shaded region represents all x values smaller than 1.

The graph is shown below.
