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).

Given: ΔАВС, m∠ACB = 90° CD ⊥ AB , m∠ACD = 60° BC = 6 cm Find CD, Area of ΔABC
gregori [183]
Area=1/2*base*height
given that ABC is right angled triangle, the height will be given by:
tan theta=opposite/adjacent
tan 60=h/6
h=6tan60
=10.4
thus the area will be:
A=1/2x6x10.4
=31.2 cm^2
