Answer 2

Finding the Area of the Function Y = 3x + 7

To find the area under the curve of the function Y = 3x + 7, we need to determine the limits of integration. Without specific limits provided, we will assume that we need to find the area between two x-values, let's say x = a and x = b.

The formula to find the area under a curve between two x-values is given by the definite integral:

Area = ∫[a to b] (3x + 7) dx

To solve this integral, we can use the power rule of integration. The power rule states that the integral of x^n with respect to x is (1/(n+1)) * x^(n+1), where n is any real number except -1.

Applying the power rule to the integral of (3x + 7) dx, we get:

Area = (1/2) * (3x^2 + 7x) |[a to b]

To find the area between x = a and x = b, we substitute b and a into the expression and subtract the result at a from the result at b:

Area = (1/2) * [(3b^2 + 7b) - (3a^2 + 7a)]

This expression gives us the area under the curve Y = 3x + 7 between x = a and x = b.

Please provide the specific values of a and b to calculate the area under the curve.
