Determine which graph represents a reflection across the x-axis of f(x) = 3(1.5)x. image for option 1 image for option 2 image for option 3 image for option 4

the equation of the function which is reflected across x-axis

f(x)=

drawn the graph on desmos graphing

and just through simple observation as the curve passes through (0,3),the reflected image must pass through (0,-3).   the image of curve after reflection:

f(x)=

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
