Answer:
1) f(x) = 7x - 3, find F(-2), f(4), and f(O)
- f(-2) = 7(-2) - 3
f(-2) = -14 - 3
f(-2) = -17
- f(4) = 7(4) - 3
f(4) = 28 - 3
f(4) = 25
- f(0) = 7(0) - 3
f(0) = 0 -3
f(0) = -3
2) g(x) = 5 - 2x, find g(-3), g(0) and g(1)
- g(-3) = 5 - 2(-3)
g(-3) = 5 - (-6)
g(-3) = 5 + 6
g(-3) = 11
- g(0) = 5 - 2(0)
g(0) = 5 - 0
g(0) = 5
- g(1) = 5 - 2(1)
g(1) = 5 - 2
g(1) = 3
3) h(x) = 8 + 3x, find h(-2), h(4), and h(0)
- h(-2) = 8 + 3(-2)
h(-2) = 8 - 6
h(-2) = 2
- h(4) = 8 + 3(4)
h(4) = 8 + 12
h(4) = 20
- h(0) = 8 + 3(0)
h(0) = 8 + 0
h(0) = 8
4) k(x) = 9x - 16, find k(-1), K(0), and k(5)
- k(-1) = 9(-1) - 16
k(-1) = -9 - 16
k(-1) = 25
- k(0) = 9(0) - 16
k(0) = 0 - 16
k(-1) = -16
- k(5) = 9(5) - 16
k(5) = 45 - 16
k(5) = 29
5) A(x) = - 6x + 2, find A(-3), A(0), and A(7)
- A(-3) = -6(-3) + 2
A(-3) = 18 + 2
A(-3) = 20
- A(0) = -6(0) + 2
A(0) = 0 + 2
A(0) = 2
- A(7) = -6(7) + 2
A(7) = -42 + 2
A(7) = -40
6) T(x) = 11x + 4, find T(-1), T(4), & T(0)
- T(-1) = 11(-1) + 4
T(-1) = -11 + 4
T(-1) = -7
- T(4) = 11(4) + 4
T(4) = 44 + 4
T(4) = 48
- T(0) = 11(0) + 4
T(0) = 0 + 4
T(0) = 4
<h3>All you must do to solve these problems are to put the given numbers in place of x and solve the multiplication, addition, and subtraction.
For example, in given problem T(4), 4 replaces the x both in the parenthesis next to the T and next to the 11.</h3>
I hope this helps.
