Identify the range of the fuction shown in the graph
Viefleur [7K]

The answer would be B. -2 < x < 2 because if you look at the graph, the range would be left and right. So, the farthest to the left would be -2 and the farthest to the right would be 2.

It wouldn't be all real numbers.

F(x) = x+ + 3<br> g(x) = 4x - 3<br> Given the functions below find (f*g)(-1)
Mashutka [201]

(f×g)(-1) is -14.

Step-by-step explanation:

  • Step 1: Calculate (f×g)(x) by using the formula (f×g)(x) = f(x) × g(x)

⇒ (f×g)(x) = (x + 3)(4x - 3)

⇒ (f×g)(x) = 4x² - 3x + 12x - 9

⇒ (f×g)(x) = 4x² + 9x - 9

  • Step 2: Find (f×g)(-1) by substituting -1 in the place of x

⇒ (f×g)(-1) = 4(-1)² + 9(-1) - 9

⇒ (f×g)(-1) = 4 - 9 - 9 =-14
