Let f(x)=8^x

what function represents a transformation of f(x) by a vertical stretch with factor 2?

g(x)=8^2x

g(x)=2⋅8^x

g(x)=8 1/2^x

g(x)=12⋅8^x

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

x = 25/2304

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
