Answer:
When combining like terms, such as 2x and 3x, we add their coefficients. For example, 2x + 3x = (2+3)x = 5x.
Step-by-step explanation:
f(x) = 4^x
f(1) just means we plug 1 in for x.
4^1 = 4
So, f(1) = 4^1 = 4
Answer:
y = - 7
Step-by-step explanation:
Assuming you require the equation
The equation of a line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 3, - 7) with y- coordinate - 7, thus
y = - 7 ← equation of line
