What is the y-intercept of the equation y=0.5(4)x?

Question

jim_thompson5910 · Answer

I'm assuming that this is $$\Large y = 0.5(4)^{x}$$ correct?

anonymous · Answer

yes i think so

jim_thompson5910 · Answer

is that x above the 4 a bit?

jim_thompson5910 · Answer

If so, then...

Plug in x = 0 and evaluate to find y

$$\Large y = 0.5(4)^{x}$$ 

$$\Large y = 0.5(4)^{0}$$ 

$$\Large y = 0.5(1)$$ 

$$\Large y = 0.5$$ 

So the y-intercept is (0, 0.5)

i have no clue how to do this and im i the middle of a quiz

anonymous · Answer

properties of line
x-intercept | 0
y-intercept | 0
slope | 2.

Wolframalpha is a great resource, but it's best to lead the student to the solution via a more step-by-step application approach. 

You quote wolframalpha directly in every single answer.
