Answer:
Option a) f(x)=x^2
Step-by-step explanation:
The parent function that can be used to graph the function f(x)=-9(x+5)^2 is f(x)=x^2
<h2>
Answer: a = ¹/₂ (4 + b)</h2>
<h3>
Step-by-step explanation:</h3>
To solve for 'a' we have to make it the subject of the equation. Since there are two unknowns ('a' & 'b'), we won't get a numerical value of 'a', but an expression in terms of the second unknown 'b'.
Since 2a - b = 4 <em> [add 'b' to both sides]</em>
then 2a = 4 + b <em>[divide both sides by 2 = multiplying by ¹/₂]</em>
a = ¹/₂ (4 + b)
Answer:
x=4
Step-by-step explanation:
Here we are given the equation 3x+k =c
Here in order to solve for x , first let us bring k to the right side.
k is in addition on the left , so when we bring it to the right it gets subtracted
now we have to isolate x on the left side , 3 is in multiplication with x , so when we bring it to the right side we divide by 3
Answer: 
you are right.
they all go up into a positive region and out of a negative region
