Answer:
Step-by-step explanation:
<u>Given functions f(x) and g(x). f(x) is:</u>
<u>Converted into vertex form, it is:</u>
<u>g(x) has vertex at (-2, -14), it's vertex form is:</u>
Comparing f(x) and g(x) we see both have same x- coordinate of the vertex (x = -2).
Both have positive leading factors, therefore the vertex is their minimum point.
Function f(x) has vertex above the x-axis as y-coordinate of the vertex is positive. Hence no intersection with x-axis.
Function g(x) has negative y-coordinate of the vertex, so it has two intersections with x-axis.
Correct choice is A
Answer:
A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.
B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) It will take 5 weeks for her to save $150
Step-by-step explanation:
A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.
B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) The time to reach $150
150 = 20(w) + 50
20(w) = 150 - 50
20w = 100
w = 100/20
w = 5
It will take 5 weeks
Answer:
C. -31
Step-by-step explanation:
To solve this problem, first you have to order of operations stands for PARENTHESIS, EXPONENTS, MULTIPLY, DIVIDE, ADD, and SUBTRACT the numbers from left to right. Please Excuse My Dear Aunt Sally!
First, parenthesis.
(4+2)=6
5-6²
Then, exponent.
6²=6*6=36
5-36
Subtract numbers from left to right.
5-36=-31
As a result, the correct answer is -31.
