Answer:
Step-by-step explanation:
f(x) = 2x² + x - 3
f'(x) = 4x + 1
f'(x) = 4(-1) + 1 = -3 slope
f(x) = 2(-1)² + (-1) - 3 = -2
(-1, -2)
-2 = -3(-1) + B
B = -5 y intercept
y = -3x - 5
f(x) = 1/x² = x⁻²
f'(x) = -2x⁻³
f'(-2) = -2(-2)⁻³ = -2/-8 = 1/4 slope
y = 1/4x + B
1/4 = 1/4(-2) + B
B = 3/4
y = 1/4x + 3/4
Answer:
6
Step-by-step explanation:
Given

Solve
We start by converting the division sign to multiplication
Then, we divide -9 by 3
Then, we divide 8 by -4
Multiply -2 and -3 to give final result
Hence, is equivalent to 6
Answer:
th equation of the line can be considered a linear function equation
Step-by-step explanation:
hope it helps
You can tell if a graph is a function by the x and y value if you find the x and y values, the x cannot repeat for the graph to be a function.
Answer:
y = 5
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis.
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (2, 5) with y- coordinate 5, thus
y = 5 ← equation of line
