When it says f(x) and x is replaced with a number, it just means replace the x in the equation with that number.
(Simpler) Way to solve using the graph:
Go to where x = -4 (4 spaces right of the center) and look above and below it for the line. Wherever the line is, is the answer. So f(-4) = 2 because when x is -4, the y value is 2.
Example of solving with an equation:
f(3) = 2
f(3) = 2(3)
f(3) = 6
You create an equation for the line, than substitute -4 in to the equation.
Answer:
0, 16, and 2
Step-by-step explanation:
if tou find the zeros that are on the x-axis then y =f(x) =0
5x*(x-16)²(x-2)² =0
use de zero product rule and make each term = to 0 and find x
5x=0 so x=0/5 = 0
(x-16)² = 0 is x-16 = 0 so x=16
(x-2)²=0 is x-2=0 so x=2
Answer:
10% of 92 is 9.2
Step-by-step explanation:
u move the decimal one number forward
X = 8
We’ll combine like terms by getting all the x terms on the right, all the digits on the left.
16 = 2x
Divide both sides by 2
x = 8
