Suppose that the functions g and f are defined as follows.

Sholpan [36]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Given:

$\to g(x)= -3+2x^2 \\\\\to f(x)=9-6x$

Calculating the value of $(\frac{g}{f})(2)$ :

$\to (\frac{g}{f}) (2)= (\frac{g(x)}{f(x)}) \times (2)$

$=\frac{2x^2-3}{9-6x} \times 2\\\\=\frac{2\cdot 2^2-3}{3(3-2\cdot 2)} \\\\=\frac{2\cdot 4-3}{3(-1)}\\\\ =\frac{8-3}{-3}\\\\ =\frac{5}{-3}\\\\ = - \frac{5}{3}\\\\$

x= $- \frac{\sqrt{3}}{2}$ and x= $\frac{\sqrt{3}}{2}$ are not in the domain.

Domain: $x \belong (- \infty, -\frac{\sqrt{3}}{2})\cup (- \frac{\sqrt{3}}{2}, \frac{\sqrt{3}}{2} )\cup (\frac{\sqrt{3}}{2}, \infty)$

Evaluate u +xy, for u = 12,x = 7, and y = 4

jeka57 [31]

Answer:

Step-by-step explanation:

Plug in 12 for u, 7 for x, and 4 for y in the given expression:

u + xy = 12 + (7)(4)

Remember to follow PEMDAS. First, multiply, and then add:

u + xy = 12 + (7 * 4) = 12 + (28) = 40

40 is your answer.
