3x^2+8x-3

Step-by-step explanation:

(x+3)(3x-1)

x*3x + x*(-1) + 3x*3 + 3*(-1)

x*3x = 3x^2

x*(-1) + 3x*3 = -x+9x = 8x

3*(-1) = -3

= 3x^2+8x-3

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

the answer to the expression is 83
