Question

What is the value of fl(x) for the function fl(x) = -13 + 7(2x + 10) when x is equal to:

a) 2
b) -5
c) 0
d) 7

Answer 1

(a) 85 , (b) - 13, (c) 57, (d) 155

Step-by-step explanation:

given the function

f(x) = - 13 + 7 (2x + 10)

to evaluate , substitute the given values for x into f(x)

(a)

f(2)

= - 13 + 7(2(2) + 10)

= - 13 + 7(4 + 10)

= - 13 + 7(14)

= - 13 + 98

= 85

----------------------------------------

(b)

f(- 5)

= - 13 + 7(2(- 5) + 10)

= - 13 + 7(- 10 + 10)

= - 13 + 7(0)

= - 13 + 0

= - 13

------------------------------------------

(c)

f(0)

= - 13 + 7(2(0) + 10)

= - 13 + 7(0 + 10)

= - 13 + 7(10)

= - 13 + 70

= 57

---------------------------------------------

(d)

f(7)

= - 13 + 7(2(7) + 10)

= - 13 + 7(14 + 10)

= - 13 + 7(24)

= - 13 + 168

= 155

Answer 2

To find the value of fl(x) = -13 + 7(2x + 10), we substitute the given values of x and simplify. The results are fl(2) = 85, fl(-5) = -13, fl(0) = 57, and fl(7) = 155.

Step-by-step explanation:

The value of the function fl(x) = -13 + 7(2x + 10) can be found by substituting the given values of x into the equation and simplifying.

• For x = 2: fl(2) = -13 + 7(2*2 + 10) = -13 + 7(4 + 10) = -13 + 7(14) = -13 + 98 = 85.
• For x = -5: fl(-5) = -13 + 7(2*(-5) + 10) = -13 + 7(-10 + 10) = -13 + 7(0) = -13 + 0 = -13.
• For x = 0: fl(0) = -13 + 7(2*0 + 10) = -13 + 7(0 + 10) = -13 + 7(10) = -13 + 70 = 57.
• For x = 7: fl(7) = -13 + 7(2*7 + 10) = -13 + 7(14 + 10) = -13 + 7(24) = -13 + 168 = 155.
