First of all, we compute the points of interest, i.e. the points where the curve cuts the x axis: since the expression is already factored, we have
Which means that the roots are
Next, we can expand the function definition:
In this form, it is much easier to compute the derivative:
If we evaluate the derivative in the points of interest, we have
This means that we are looking for the equations of three lines, of which we know a point and the slope. The equation
is what we need. The three lines are:
This is the tangent at x = -2
This is the tangent at x = 0
This is the tangent at x = 1
Answer:
Bella has 415 pictures, Jesse has 83 pictures
Step-by-step explanation:
Bella:Jesse = 5:1
6x=498
x=83
Jesse has 83 pictures, Bella has 415 pictures
Answer:
70 degrees
Step-by-step explanation:
In the parallelogram KLMN, the sum of the adjacent angle is 180 degrees
Hence;
m<K + m<L = 180
110 + m<L = 180
m<L = 180-110
m<L = 70degrees
Hence the measure of m<l is 70 degrees
Step-by-step explanation:
A proportional relationship graph would show that the points can be arranged in a line that passes through the origin.
All of the points in Graphs B, C and D cannot be connected in 1 straight line, hence they are not proportional relationships.
Only Graph A shows a proportional relationship.
