Suppose f(×) = 2^×, sketch a graph of f(×) and f^-1(×)​
musickatia [10]

Let f(x) = y

y = 2^x

x = 2^y

Solve for y.

ln x = ln(2^y)

ln x = y ln 2

ln x/ln 2 = y

Replace y with f^(-1) x.

f^(-1) x = ln x/ln 2

We now know f(x) and f^(-1) x.

Use your graphing calculator to graph the function and its inverse on the same xy-plane. If you don't have a graphing calculator, use DESMOS online.

Good luck.

9) Which equation represents the line that passes through the point (3,4) and is parallel to the x-axis?
kobusy [5.1K]
Since the line is parallell to the x-axis we know the slope is zero: m=0

Using the point-slope formula we can substitute know values:
y=mx+b
4=0(3)+b
b=4
y=0x+4
y=4

You could also jsut do it by inspection: since it passes through (3,4) and is horizontal it must cross at (0,4) i.e. all y=4.

tatyana61 [14]
Ok so from experience on this site
3x2=3x^2
people don't know how to put exponents
3x^2-y^3-y^3-z
simplify first

3x^2-2y^3-z

x=3
y=-2
z=-5
3(3^2)-2(-2)^3-(-5)
