I will named this exponential function as y= - 343^x .
This function is symmetrical with function y = 343^x in relation to X axis.
In general their formula is y=a^x or in your case y= - a^x
First I'll describe y=a^x => this function has domein Dx=R ( Whole field of real number), range is in interval ( 0, +infinity), when x increases and y increases, when x decreases and y decreases. This function is always positive in whole domain and always is growing function. And X axis is its asymptote (y=0).
In your case function y= - 343^x has folowing features:
domein Dx=R
range is in interval (-infinity, 0)
when x increases => y decreases =>
example: y= -2^2=-4, y= -2^3=-8 etc....
when x decreases => y increases ->
example: y= -2^(-2)= - 1/(2^2)= - 1/4, y=-2^(-3)= - 1/(2^3)= - 1/8 etc....
this function is always negative
this function is always declining
x axis is its asymptote from the top ( y=0)
Answer:
a) x=-15
b) x= 27
c) x=14
Step-by-step explanation:
a) x/-3+1=6 x/-3=5 (-3)x/-3=5(-3) x=-15
-1 -1
b) 3-x/9=0 -x/9=-3 (-9) -x/9=-3(-9) x=27
-3 -3
c) x/-2+4=-3 x/-2= -7 (-2)x/-2= -7(-2) x=14
-4 -4
Answer:
-a/b
Step-by-step explanation:
ax+by=c
First get the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
Subtract ax from each side
ax+by -ax=-ax +c
by = -ax+c
Divide each side by b
by/b = -ax/b + c/b
y = -a/b * x + c/b
The slope is -a/b and the y intercept is c/b
We want the line parallel so it has the same slope, -a/b
