EXPLANATION: Simply substitute the value of 3 given. In other words, f(3) is the function of f(x), however, in this case, x is 3
f(3)=3(3)−4
Distribute 3 through the parenthesis
f(3)=9−4
Simplifyf(3)=5
Step-by-step explanation:
Answer:
2x^2 +11
Step-by-step explanation:
f(x) = 3x^2 +2
g(x) = x^2 -9
f(x) - g(x) = 3x^2 +2 - (x^2 -9)
Distribute the minus sign
= 3x^2 +2 -x^2 +9
Combine like terms
= 2x^2 +11
Well it's similar because it uses the numbers to number the line and used as measurements and it's different because it has more precise measurements for whatever it is that u r doing
Answer:
substitute the input (the given number or expression) for the function's variable (place holder, x).
Replace the x with the number or expression.
Example:
f(x)=3x-5 and f(4)
f(x)=3(4)-5
f(x)=12-5
f(x)=7
final answer is (4,7)
Answer:
1 : 140
Step-by-step explanation:
The scale used to make the model of height 4.2 feet = 1.28016m of a skyscraper (a very tall building) of height 525m is given as:
1.28016/525
= 1 : 410.156
≈ 1 : 410
