Let g(x) = 2x and h(x) = x^2 +4. evaluate (g• h) (3)

Step-by-step explanation:

g(x) = 2x

h(x) = x² + 4

To find (g• h) (3) first find ( g • h)(x)

To find ( g • h)(x) substitute h(x) into every x in g(x)

That's

( g • h)(x) = 2( x² + 4)

( g • h)(x) = 2x² + 8

Now substitute 3 into ( g • h)(x)

(g• h) (3) = 2(3)² + 8

= 2(9) + 8

= 18 + 8

where is the triangle?

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
