3. Suppose f(3) = 4 and f'(3) = 2. Let g() = 2f(3x). Find the equation of the line
tangent to g(x) at x = 1.
please help, I dont understand it

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
