Evaluate the function at the indicated values. f(x)= 6x^2+ 5x -12
seropon [69]

Step-by-step explanation:

We need to find the value of the function at the indicated value.

f(x)= 6x^2+ 5x -12

Indicated values are : f(-7), f(0), f(6), f(7)

To find f(-7), put x = -7 in the given function

f(-7)= 6(-7)^2+ 5(-7) -12=247

To find f(0), put x = 0 in the given function

f(0)= 6(0)^2+ 5(0) -12=-12

To find f(6), put x = 6 in the given function

f(6)= 6(6)^2+ 5(6) -12=234

To find f(7), put x = 7 in the given function

f(7)= 6(7)^2+ 5(7) -12=317

Hence, this is the required solution.

Hi there!

To answer this, we must set it up as

Now we just use the distributive property to solve.

this becomes 6x^5-36x^3+21x
