Answer:
The graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).
Step-by-step explanation:
We know that when we add a constant to the input of the parent function, we get a horizontal shift.
The direction of shifting depends upon the value of the added constantly. If the added constant is negative, the shift of the graph will be left and if the added constant is positive, the shift of the graph will be right.
For example, consider the function
f(x)
so adding 
in the put i.e. 
would be a change on the inside of the function, giving a horizontal shift left by 3.
Therefore, the graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).
Answer:
2x² + 3x
Step-by-step explanation:
Using distributive property, you can multiply the variable outside the parenthesis to both terms inside the parenthesis:
x(2x + 3) = 2x(x) + 3(x) or 2x² + 3x
When multiplying with the same base, you will add the exponents.
Answer:
the two possibilities are either 35.5m orrr 65m
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
This factors to the product of 2 binomials like (x + a)(x + b), where a and b are 2 numbers.
40 = 4 * 10 and 14 = 4 + 10 so the answer is
(x + 4)(x + 10).
If we expand this we will get back to the quadratic expression:
(x + 4)(x + 10)
= x(x + 10) + 4(x + 10)
= x^2 + 10x + 4x + 40
= x^2 + 14x + 40.
Ok so important numbers 42 ft, 2cm, 3 ft and lets take height as x
if 2cm=3ft than x cm= 42 ft
2 = 3
-------
x= 42
cross multiply divide
(42)2/3
84/3
28
