From the dots the parabola’s are the same size just transitioned to different locations.
blue = y = x^2 + 3
Green = y = (x-4)^2
Orange = y = x^2 - 3
Purple = y = (x+4)^2
Answer:
B
Step-by-step explanation:
Slope of the line is -3. y-intercept is 3.
So, the rule for this line is y= - 3x+3.
The pattern of y-values that can fit is B.
y=0, x= 1
y=-3, x=2
y=-6, x=3
and so on.
Answer:
see below
Step-by-step explanation:
The ratio of map distance to actual distance is a constant (for a map of a sufficiently small area).
(0.5 in) / (25 mi) = (map distance between cities) / (725 mi)
1.Since 5 is less than 8, borrow 1 from the next column to make 15.
2.Calculate 15 - 8, which is 7.
3.Calculate 3 - 3, which is 0.
4.Since 2 is less than 5, borrow 1 from the next column to make 12.
5.Calculate 12 - 5, which is 7.
6..<span>Calculate 9 - 2, which is 7.</span>
7.<span>Therefore, 102.45 - 25.38 = 77.07.</span>
There are no numbers on the graph, so we cannot tell for sure the value of f(3).
If the grid squares are each one unit, then the graph of f(x) appears to go through the grid point (3, -1). This means f(3) = -1.
Using this value in the expression for g(x), we have
.. g(3) = -4*f(3) +7
.. g(3) = -4*(-1) +7
.. = 4 +7
.. = 11
The value of g(3) is 11.
