This problem is a difference of squares. So to solve this you want to factor it out so you get two numbers that multiple to -9 and add to 0. That would be -3 and 3
f(x)=(x-3)(x+3)
So your solution when you set f(x) to 0 would be -3 and 3.
Answer:
Option D is correct.
Step-by-step explanation:
An exponential function is in the form of
where a is the initial value and b≠ 0 , b >1 .
Given: The function f(x) = y =
......[1]
The domain is all real numbers and the range is y > 0.
y-intercept defined as the graph crosses the y-axis.
Substitute the value of x= 0 in [1] to solve for y;
y =
= 4
y-intercept = (0, 4)
End behavior:
when b =3 >1
then;
as
,
as
,
therefore, the only graph which represents the function y =
is Option D
(3x+1) = 64
3x = 63
3x/3 = 63/3
x = 21
