Find the x-intercept of y = 4 ^ x - 64 .

The x-intercept is (3,0)

Step-by-step explanation:

First to find x intercept you need to substitute y for 0 as the x-axis is just the line y=0. After doing this we find:

⇒ 4^x-64=0

add 64

4^x=64

The two methods to solve are either:

Figure out that 64=4^3 so:

4^3=4^x

and so the solution must be x=3 because of the rule: a^b=a^c, b=c

The other way is to use logarithms so

a) false; the points do not have to be in a straight line.

step-by-step explanation:

the points could be in the shape of a triangle

b is incorrect

c is incorrect because it is saying the immediately don't form one when they are capable of doing so

d is incorrect
