Answer: f(x)=2-x^2
Step-by-step explanation:
The quadratic equation is
y=ax^2+bx+c
and c is equal to the y-intercept.
in the twi graphs shown both have the same shape but different y-intervepts.
c(the y-intercept) in the first graph is 5 and in the second graph(F) is 2.
Answer:
A
Step-by-step explanation:
in x<-4 the derivative is positive so the function is increasing.
in x>-4 the derivative is negative so the function is decreasing
increasing in (-infinity,-4)
decreasing in (-4,infinity)
Answer:
549
Step-by-step explanation:
The next larger whole number, 550, will round up to 600.
The largest whole number that rounds to 500 is 549 when rounding to hundreds.
For this case, what you must do is take out the area of two triangles and add it to the area of a rectangle to find the total area.
We have then:
Triangle area:
A = (1/2) * ((13-9) / (2)) * (10) = 10 in ^ 2
Rectangle area:
A = (9) * (10) = 90 in ^ 2
Total area:
At = 2 * (10) + 90 = 110 in ^ 2
answer:
110 in²
