The graph of y=f(x) is shown above. Which of the following could be the graph of y=f′′(x)?.
AfilCa [17]

The true statement about the graph of f(x) is f(x) = \frac 35x + 3

The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).

Start by calculating the slope (m)

m = \frac{y_2 - y_1}{x_2 -x_1}

So, we have:

m = \frac{3-0}{0--5}

Simplify

m = \frac{3}{5}

The equation of the line is then calculated as:

y = m(x -x_1) + y_1

This gives

y = \frac 35(x -0) + 3

Open bracket

y = \frac 35x + 3

Express y as a function of x

f(x) = \frac 35x + 3

Hence, the true statement about the graph of f(x) is f(x) = \frac 35x + 3

Fofino [41]

During a research work, an effective and efficient way to follow the scientific method includes:

Make observations.

Ask questions.

Construct a hypothesis.

Test the hypothesis with an investigation.

Analyze the data.

Explain the result.

Communicate the result.

The scientific method is the variety of techniques that scientists use to observe, examine, investigate, and study the natural world and explain it based on evidence, theories, evidence, hypotheses, or factual information that scientists derive from their research work.

It can be defined as the scientific method usually involves combining traditional scientific processes with critical thinking, scientific knowledge, and reasoning to generate new ideas. Please note that if your hypothes is true, it should be shared with the community. However, if your hypothesis is wrong, you should build another hypothesis and repeat the process.
