Question

Help me please i have one more and then i can be done with the IXL

Answer 1

Explanation:

We have :

`f(x) = \left \{ {{2x+ 4\;\;\;\;\;\;if\; -5\leq x\leq 1} \atop {-x+7}\;\;\;\;\;\;\;\;if\; 1 < x < 5} \right. \\\\`

When x = -5,

f(x) = 2(-5) + 4

f(x) = -10 + 4

f(x) = -6

When x = 1,

f(x) = 2(1) + 4

f(x) = 2 + 4

f(x) = 6

When x = 2,

f(x) = -2 + 7

f(x) = 5

When x = 4,

f(x) = -4 + 7

f(x) = 3

Plot these points on the graph.

The red line indicates f(x) = 2x + 4 and the blue line indicates f(x) = -x + 7
