ANSWER

EXPLANATION
The given function is a piecewise defined function.

is the y-value that corresponds to

To determine that y-value, we need to trace from

to where it meets the graph.
We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.
From the graph, we can see that this x-value corresponds to a y-value of

This implies that, when

Therefore

See graph.
Answer:
Y=3x + 4
Step-by-step explanation:
Gradient = rise/run
=9/3
=3
Y-intercept is also 4
Answer:
For the first equation the answer for "X" will be,

if you want me to solve for y instead then the answer will be,

for the second equation the answer for "X" will be,

If you want me to solve for y instead then the answer will be,
