Domain: (-∞,∞)
Range: (3,∞)
x-intercepts: none
y-intercepts: (0,7)
Interval positive: (3,∞)
Interval negative: none
Interval increasing: (7,∞)
Interval decreasing: (-∞,7)
I'm not sure what the average rate of change over is though.
Answer:
Your answers would be:
x = 10 and x = -8
Step-by-step explanation:
Solve for the zeros:
x² - 2x - 78 = 2
Subtract both sides by 2.
x² - 2x - 80 = 0
Use the quadratic formula: 
a = 1
b = -2
c = -80
Plug in and solve:

Solve for +:

Solve for -:

Answer:
m<3 = 90
C
Step-by-step explanation:
This is a kite. The diagonals intersect each other in such a way that m<1 and m<3 are at right angles. m<3 = 90o
Answer:
8.1146
Step-by-step explanation:
easy :)
Answer:
8 and 3
Step-by-step explanation:
We first want to add 5 to both sides, making the equation x^2 -11x +24=0, now, we want to use the quadratic formula, which is( -b <u>+</u> sqrt(b^2 -4ac)) /2a
for equations of the form ax^2 + bx +c, so in our case, a =1, b= -11, and c=24,
when you plug in the variables, you will get the answers! :)
