It’s A because rise/run
Rise is y and run is x because the run is going left it’s a negative
Answer:
(1.5,2.5)
Step-by-step explanation:
f(x) = 2x^2 - 6x + 7
Take the first derivative and set it equal to 0 (the slope is 0 at the vertex)
f'(x) = 4x -6
0 = 4x - 6
4x = 6
x = 3/2 or 1.5
If x = (3/2), then y = 2(3/2)^2 - 6(3/2) + 7
y = 2(9/4) - 18/2 + 7
y = (9/2) - 2
y = 2.5
See attached graph.
Y = -3x + c
Using (1,-5):
-5 = -3(1) + c
c = -5 + 3(1) = -2
Therefore:
y = -3x - 2
Answer:
No
Step-by-step explanation:
No. You can see why if you remove the brackets.
y=x^2 - 3x.
A linear function must have x and y with powers of 1. Also it can't something like x^2 - y^2 = 5
x^2 - y^2 = 0 is the only exception I can think of, but that really is a system of equations. If you graph it. you get two equations which cross at 0 and nowhere else.
