Ans(a):
Given function is 
we know that any rational function is not defined when denominator is 0 so that means denominator x+4 can't be 0
so let's solve
x+4≠0 for x
x≠0-4
x≠-4
Hence at x=4, function can't have solution.
Ans(b):
We know that vertical shift occurs when we add something on the right side of function so vertical shift by 4 units means add 4 to f(x)
so we get:
g(x)=f(x)+4
We may simplify this equation but that is not compulsory.
Comparision:
Graph of g(x) will be just 4 unit upward than graph of f(x).
Ans(c):
To find value of x when g(x)=8, just plug g(x)=8 in previous equation
4x+16=3x-1
4x-3x=-1-16
x=-17
Hence final answer is x=-17
Answer:
b. The boundary line of y < 2x - 3 is not a solid line.
Step-by-step explanation:
It's a linear inequality thus its boundary line must be a solid line.
Answer:
Step-by-step explanation:
Please, if you're indicating exponentiation, use the symbol " ^ " to indicate it. Thanks.
The parent function here is f(x) = x^3.
g(x) = (x + 6)^3 has the same graph as does
f(x) = x^3, except that the entire graph of x^3 is translated 6 units to the left.
h(x) = -(x + 6)^3 has the same graph as
does g(x), except that the entire graph of g(x) is reflected in the x-axis.
The graph of h(x) = h(x) = –(x + 6)3 – 3 is the same as that of h(x) except that the entire graph is translated downward by 3 units.
Take the original price and multiply it by the percentage (not in percentage form) and divide it by 100
(7*15)/100=1.05
<u>$1.05 is the discount
</u>
7-1.05=5.95
<u>$5.95 is the ticket cost on a weekday</u>
