The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)

<h3>What are exponential functions?</h3>

When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.

here usual form is specified below. They are written in several such equivalent forms.

The equation of the function is given as:

f(x)=3(2)^x -4

Set x = 0, 1, 2 and 3

f(0)=3(2)^0 -4 = -1\\f(1) = 3(2)^1 - 4 = 2\\f(2) = 3(2)^2- 4 = 8\\\\f(3) = 3(2)^3 - 4 = 20

This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).

Answer:

\mathsf {y =\frac{15}{7}x } < \mathsf {y=\frac{13}{6}x } < \mathsf {y=\frac{11}{5}x } < \mathsf {y=\frac{21}{9}x } < \mathsf {y= \frac{19}{8}x}

Step-by-step explanation:

<u>Finding the unit rate of the graph</u> :

  • Take 2 points and find the slope
  • ⇒ (0,0) and (12, 25)
  • ⇒ m = 25 - 0 / 12 - 0
  • ⇒ m = <u>25/12</u>
  • The equation is : <u>y = 25/12x</u>

Now, the equations with greater unit rates (in increasing order) are :

  • \mathsf {y =\frac{15}{7}x } < \mathsf {y=\frac{13}{6}x } < \mathsf {y=\frac{11}{5}x } < \mathsf {y=\frac{21}{9}x } < \mathsf {y= \frac{19}{8}x}

Trigonometric identities assignment 4
kykrilka [37]

Answer:

<em>Answer: choice D.</em>

Step-by-step explanation:

<u>Trigonometric Functions</u>

We need to recall some properties and definitions of the trigonometric functions.

\displaystyle \tan \theta=\frac{\sin\theta}{\cos\theta}

\displaystyle \sec \theta=\frac{1}{\cos\theta}

We need to simplify the following expression:

5\sin\theta\sec\theta

Substituting the identity for the secant:

\displaystyle 5\sin\theta\sec\theta=5\sin\theta.\frac{1}{\cos\theta}

Operating:

\displaystyle 5\sin\theta\sec\theta=5\frac{\sin\theta}{\cos\theta}

Substituting the definition of the tangent:

\displaystyle 5\sin\theta\sec\theta=5\tan\theta

Correct choice D.
